  Caitlin had her instant-messaging program set to load at Windows startup. He clicked on the little icon in the system tray, and the chat window appeared. Among her buddies listed as being online was Webmind; of course—where else could he be? He clicked on the name and typed Hello.

  There was no response, so he tried again: Are you there?

  Still nothing.

  And then he realized what, perhaps, the problem was, and he was pleased, even though it was by logical reasoning and not empathy that he worked it out: Webmind saw through his daughter’s eye; he doubtless knew that she was at school; he was therefore afraid he had been detected by an outsider. And so he wrote, This is Malcolm G. Decter.

  The response was instantaneous: Greetings, Professor Decter.

  Malcolm smiled; Webmind had paid attention while he and Caitlin were watching WarGames.

  Caitlin thinks you have emotions, he typed, but I suspect this is not possible, as you lack the evolutionary history that gave them to humans.

  Webmind responded instantly: You think that she thinks that I think that you think that she thinks that you don’t think that I have emotions.

  Malcolm found himself smiling again, and wondered what algorithms one might employ to simulate a sense of humor.

  Exactly. However, whether you have emotions or not, it is possible to give responses that will make—

  He’d started to type “neurotypicals,” but backspaced over it.

  —people feel comfortable interacting with you.

  Indeed, said Webmind. Do tell.

  And so he did.

  “You like who?” Bashira said, as they visited the girls’ restroom after English class.

  “Matt,” Caitlin replied.

  Bash feigned not having heard correctly. “I’m sorry. I thought you said Matt.”

  They were standing by the row of sinks. “I did.”

  “Guy you were helping in math? Matt—what is it? Matt Royce?”

  “Reese, and, yes, that’s him—although he hardly needed my help. He knows almost as much as I do.”

  “Um, Cait, babe, I know you’re new to this seeing thing, but . . .”

  “Yes?”

  “He’s not exactly good-looking.”

  “He’s symmetrical.”

  “Sure he is—that harelip bisects his face nicely.”

  “I like the way he looks. I like his eyes.”

  Another girl came into the room and headed for one of the stalls. Bashira lowered her voice. “I know when you fall off a horse, you’re supposed to get right back on—but they don’t mean an actual horse, you know. You can do so much better.”

  “Better than someone who shares my interests? Someone who is kind?”

  Bashira pointed at the long sheet-metal mirror above the sinks. “Cait, have you looked at yourself in the mirror?”

  “From time to time.”

  “You’ve got it going on, girl. You’re hot.”

  “Well, that’s nice, I suppose, but—”

  “You could have anyone.”

  “Is that all anybody cares about? How people look?”

  “Well, no, but . . .”

  “Besides, my mother and I were talking about this earlier. I get to choose who I find attractive.”

  “You can’t just choose that,” Bashira said.

  “No? What are you going to do when you get married? Your parents are going to arrange a marriage for you, right?”

  “Well, that’s what they want to do, yes,” said Bashira.

  “So, what if it’s someone you don’t find attractive at first? Are you going to go through life thinking he’s ugly, or are you going to choose to find him good-looking?”

  “I . . . I don’t know,” Bashira said. “I don’t think you can . . . can program yourself that way.”

  “Oh, yes, you can,” said Caitlin. “You totally can.”

  “But, anyway, it’s not just about what you think,” Bashira said. “It’s about what other people think about Matt’s looks. They’ll judge your stature by who you’re with.”

  “It isn’t all about hierarchies,” said Caitlin. “We’re not apes, you know.”

  “But, Cait, don’t you see? You could have Trevor.”

  “I don’t want him. Not anymore. I want Matt.” And then she added, unkindly, “You can have Trevor.”

  Another facial expression Caitlin had never seen before, but she imagined it was what books referred to as looking crestfallen. “No, I can’t,” Bashira said softly after a moment. “You know that. My parents would kill me. I—I have to live vicariously through you.”

  Caitlin was startled when the words Join the club flashed across her vision.

  Caitlin had missed a lot of school already, what with the trip to Japan to have the implant inserted behind her eye, with the days she’d spent after gaining sight learning to interpret what she was seeing, and with the press conference to announce Dr. Kuroda’s success. But when she had gone to school, she’d always eaten in the cafeteria—and she knew that was where Trevor ate, too. And so when she and Matt rendezvoused outside the cafeteria’s doors, she said, “Why don’t we go somewhere else for lunch?”

  He lifted his pale eyebrows. “Um, sure, okay. How ’bout Timmy’s?”

  “What’s that?”

  Matt smiled. “Right, right. You’re new to Canada. ‘Timmy’s’ is Tim Hortons. It’s, like, the number-one donut chain here—but they’ve also got good sandwiches, soups, and stuff like that. There’s one just a block away.”

  Caitlin had heard the company’s commercials on TV, and, huge hockey fan that she was, she knew who Tim Horton had been: twenty-two seasons as a defenseman in the NHL, playing for the Leafs, the Rangers, the Penguins, and the Sabres.

  They went by their lockers to dump stuff and get their jackets. Caitlin told Matt not to bother to lug his math textbook along, which made him smile—and then they headed outdoors. The sky was filled with clouds. As they walked along, Matt fell in on Caitlin’s right side, but that was the side she was blind on. Suddenly, stupidly, she didn’t want to explain that fact—she didn’t want to be anything less than perfect just then. And so she let him walk on that side, and she turned her head probably more often than was normal so that she could see him now and then.

  As they came close to the donut shop, and she looked at the big sign, she was puzzled. The name was written in a kind of script that was difficult for her to read, but the one thing she should have been able to pick out—the apostrophe—seemed to be missing. “I don’t understand,” she said. “Why is it Hortons, plural?”

  Matt laughed. “Well, it used to be Tim Horton’s—possessive, with an apostrophe-s. But, see, an apostrophe-s makes it English. And Quebec has this law against English-language signs. So lots of companies changed their names so they could use the same signage across Canada. ‘Tim Hortons’ without an apostrophe is just a name—not English or French—so it’s allowed. But look at that Wendy’s over there.” He pointed across the street.

  “Which one is it?”

  “Sorry. The building on the left.”

  “Yes?” said Caitlin

  “Look at the end of the name.”

  “Oh! What the heck is that?”

  “It’s a maple leaf. Where they’d have the apostrophe in the name in the States, they’ve got a maple leaf here. Applebee’s and Denny’s do the same thing: A-p-p-l-e-b-e-e, maple leaf, s, and D-e-n-n-y, maple leaf, s.”

  “This is one wack-job country you got here, Matt.”

  He laughed again. “We make it work somehow. I mean, it’s a small thing for English Canada, and it makes French Canada happy, so why the heck not? Yeah, the cloning of Tim Horton is kinda crazy, I’ll give you that. But all the maple leaves are cool.”

  They went into the Hortons, and Matt read the menu to her, explaining what kinds of sandwiches they offered—she could have read it herself, given time, but there were people in line behind them. She ordered chicken salad on a whole
-wheat bun, a chocolate glazed donut, and a Coke. He ordered sliced turkey on a regular bun and a small coffee.

  Caitlin opened her wallet—and found herself pausing to stare. She still had her bills folded in distinctive ways so that she could tell a five from a ten from a twenty by touch. But now she could read the large, clear numerals on the Canadian bills—not to mention see that the five was blue, the ten purple, and the twenty green. Would wonders never cease?

  Realizing she was holding up the line, Caitlin handed over a ten, took her change, and then followed Matt to a table in a corner—one of those modular ones with chairs attached to it. “So,” she said, after some chitchat that she had to admit was pretty lame, “do you—um, do you have a girlfriend?” She was amazed at how dry her mouth had suddenly become.

  She was surprised to see him appear—hurt, perhaps? Like maybe he thought she was teasing him. But at last he said simply, “No.”

  She looked away, in case she was making him uncomfortable, and pleased herself by the figurative and—at that precise moment, literal—truth of her reply: “I’m not seeing anyone, either.”

  He took a bite of his sandwich, and she took a bite of hers. She was afraid to say anything else, but—

  But she was Barbara Decter’s daughter, for Pete’s sake! And her mother had told her, years ago, when Caitlin had asked about her parents’ relationship, that she had asked her father out the first time, and, eighteen months later, that it had been her, not him, who had popped the big question.

  So, hell, she wouldn’t even be here if her mother had been too shy to make the first move—and the second, and the third, and . . .

  “Um,” she said, and “ah,” and then, disappointing herself with the quality of her rhetoric, she let loose with another “um.” Online she was fearless—she was Calculass! But here, in the real world, she was just Caitlin, and sometimes, especially when having to deal with people stuff, she felt more like her father’s daughter than her mother’s. She took a deep breath and tried to summon the strength of her alter ego. Then she looked down at her sandwich, and, when she forced the words out they came in a rush, without any pauses: “So would you like to go out sometime?”

  Caitlin, of course, counted the seconds.

  One. Two. Three.

  She resisted the urge to look up him, afraid of the expression she might see.

  Four. Five. Six.

  “You want to go out with me?” he said, at last, sounding stunned.

  She did lift her gaze. “Yes, silly.”

  “I, uh, I thought you were going with Trevor. I, um, I mean, didn’t he take you to the dance?”

  “Were you there?”

  “Me?” He seemed astounded at the suggestion. “No.”

  “Trevor’s a jerk,” she said. “And, no, I’m not going out with him. So, how ’bout it? Wanna go out sometime?”

  “Well,” he said, and “um,” and, at last, “yes.”

  “Great,” said Caitlin. She paused, waiting for him to make a suggestion, but when he didn’t she said, “There’s an awesome series of free public lectures at the Perimeter Institute. Have you ever been to any of those?”

  “No. I’ve tried. The tickets are impossible to get. They go like that.” He snapped his fingers as he spoke the final word.

  “I’ve got an in. My dad is on the lecture committee there.”

  “Your dad works at PI?”

  “Uh-huh. He studies quantum gravity.”

  “Cool!”

  Caitlin smiled. Who’d have thought her dad would turn out to be cool?

  Suddenly, Braille dots flowed in front of her eyes. If I may be so bold, Caitlin, you should inquire about what he hopes to do after high school.

  Caitlin wanted to ask what the hell Webmind was doing, but there was no way to do so with Matt right there. Still, it did seem like a good way to keep the conversation going, so she posed the suggested question.

  “I’m going to do computer science.”

  Ask him where.

  “Where?”

  “Here,” he said. “There’s nowhere better than the University of Waterloo.”

  “Really? I’ve always had my heart set on MIT.”

  “Well,” said Matt, “you should check out what’s here, too.”

  Ask him what his favorite color is.

  Caitlin couldn’t stand it anymore. “What are you doing?” she said into the air.

  I read all of Project Gutenberg, Webmind replied at once, including the play Cyrano de Bergerac. I thought I’d lend a hand.

  “Sorry,” said Matt. “I, um, I always eat my sandwich that way.”

  Caitlin had too little experience with watching people eat to be able to identify whatever Matt had done that was unusual. “Ah,” she said, and smiled at him. “That’s okay. It’s cute.”

  twenty-five

  Caitlin had heard her mom use the phrase “nonzero-sum” from time to time. She knew it was a term from her mother’s field of expertise, game theory. Webmind had already read everything on Wikipedia about game theory, but that didn’t mean he actually understood what “nonzero-sum” meant. Nor, if she was really honest with herself, did Caitlin, and yet this notion of nonzero-sum games was stuck in her mind: win-win situations in which everything could be made better.

  Her mother had been having her own conversations with Webmind all day long while Caitlin was at school. Once Caitlin got home and had checked her email and so forth, she went across the hall to her mother’s office and told her about that poor Australian girl who had committed suicide, and about how she’d told Webmind that he should intervene in nonzero-sum situations.

  Her mom looked horrified. “It just . . . just watched her kill herself? It didn’t try to stop her?”

  “He, Mom. He didn’t know what to do, what to think. We need him to understand what to do the next time, and not just with teen suicides, but in any nonzero-sum situations. Can you help us?”

  Her mother’s face moved through several expressions but then settled on one that Caitlin had seen before: the take-charge, supermotherscan-do-everything face. “Yes, I’ll help it—help him—learn to help the rest of us. That’s something I definitely want in on.”

  “Thanks,” replied Caitlin. “But, I mean, I know—we know—what nonzero-sum is; we get that. But there must be a lot more to game theory than just that.”

  “Oh . . . a bit,” said her mother. Caitlin realized she was still coming to grips with the magnitude—the importance—of what she was about to do.

  “So, could you explain it to us? I remember hearing you say once that game theory really isn’t just about mathematics, but about human psychology.”

  “That’s right,” her mother said. “In fact, the hottest branch of game theory right now is called ‘behavioral game theory.’ ”

  “Well, Webmind certainly needs to understand human behavior better.”

  So everyone keeps saying, Webmind sent to her eye.

  “Okay,” said her mom. “Let’s go downstairs.”

  Her mother got a clipboard, some pens, and some paper, and the two of them went to the dining room, which had a big table. There was normally one chair on each side of the table, but Caitlin’s mom moved hers to be next to Caitlin’s.

  “Webmind is listening, right?” asked her mom.

  The word Yes flashed in Caitlin’s vision, and she repeated it.

  “Okay,” her mom said. “Do you know what the prisoner’s dilemma is?”

  Caitlin thought, How to pick up the soap in the shower? But what she said was, “No.”

  Her mother seemed to consider for a moment, then: “Okay, let’s do it like this: say you and Bashira both get in trouble at school. Say Principal Auerbach has said that he thinks you guys have hacked into the school’s computer and changed your grades—just like in WarGames, right? And he talks to each of you separately. He says to you, ‘Okay, look, Caitlin, I admit I haven’t got enough evidence to actually prove you did this, but I can suspend each of you for a week just
because, well, because I’m the principal.’ ”

  Caitlin nodded, and her mother went on. “But the principal’s real interest is in making sure this never happens again, so he adds that if you’ll say Bashira did it and explain how it was done, you get off scot-free—no suspension at all—and he’ll suspend Bashira for three weeks. Oh, except for this: if you say Bashira did it, and Bashira says you did—that is, if you each blame the other—then you’ll both get suspended for two weeks. Got that? You can end up with no suspension, one week’s worth, two weeks’ worth, or three weeks’ worth. And you know he’s going to make the same offer in private to Bashira. What do you do?”

  Caitlin didn’t hesitate. “I clam up; I don’t say a word.”

  “But if Bashira fingers you, you’ll get three weeks of suspension.”

  “But she won’t,” Caitlin said firmly.

  Her mother seemed to consider this. “Okay, okay, let’s say it’s not you and Bashira for the moment. Let’s say it’s just two random guys—um, Frank and Dale. What should you do if you’re Frank?”

  Caitlin suppressed a smile. Frank was the name of her mother’s first husband, who had come and gone long before she’d been born, and Dale, she knew, was the former head of the Economics Department at the University of Houston—someone her mother had famously not gotten along with. Picking truly random people was as hard as generating really random numbers, it seemed.

  Still, the math was easy. “I rat out Dale,” Caitlin said.

  “Why?”

  “Because it’s the best thing for me. If he doesn’t rat me out, I get away without any punishment, instead of having a one-week suspension. And if he does rat me out, then I’m still better off, because then I only get a two-week suspension, instead of the three weeks I’d have gotten by keeping my mouth shut. No matter what he does, I cut a week off my punishment by ratting him out.”
