“This is what I say: I've got good news and bad news.The good news is, you don't have to worry, you can't change the past.The bad news is, you don't have to worry, no matter how hard you try, you can't change the past.The universe just doesn't put up with that. We aren't important enough. No one is. Even in our own lives. We're not strong enough, willful enough, skilled enough in chronodiegetic manipulation to be able to just accidentally change the entire course of anything, even ourselves.”

“She says that is exactly what she's crying about. That everything is all right. That the world isn't ending. That we'll never tell each other how we really feel because everything is okay. Okay enough to just sit around, being okay. Okay enough that we forget we don't have long, that it's late, late in this universe, and at some point in the future, it's not going to be okay.”

“I don't know what I would do without you. I don't know what I will do without you. I learned about the future tense, how anxiety is encoded into our sentences, our conditionals, our thoughts, how worry is encoded into language itself, into grammar.”

“Sometimes at night I worry about TAMMY. I worry that she might get tired of it all. Tired of running at sixty-six terahertz, tired of all those processing cycles, every second of every hour of every day. I worry that one of these cycles she might just halt her own subroutine and commit software suicide. And then I would have to do an error report, and I don't know how I would even begin to explain that to Microsoft.”

“Who do you imagine you are? Imagine there's a version of you that sees all of it. A version that knows when versions are messing with the other ones, trying to get things off track, trying to erase things. A record of all the versions, partial and deleted and written over. All the changes. All truths about all parts of our self. We break ourselves up into parts. To lie to ourselves, to hide things from ourselves. You are not you. You are not what you think you are. You are bigger than you think. More complicated than you think. You are the only version of you that is you. There are less of you than you think, and more. There are a million versions of you, half a trillion. One for every particle, every quantum coin flip. Imagine this uncountable number of yous. You don't always have your own best interests at heart. It's true. You are your own best friend and your own worst enemy. . . . Only you know what you need to do. Imagine there is a perfect version of you. Out of all the oceans of oceans of you, there is exactly one who is perfectly you. And that's me. And I'm telling you that you are the only you.”

“If I could tell him just one thing, wherever he is, pass him one message, it would be this: he had something. Something to his thoughts, his ideas, the papers in his notebooks, the work we did in the garage. Beyond just a purity to his ideas, a sincerity to his belief, a genuine curiosity, a determination that, if he just sat there long enough, thought hard enough, failed enough times, he'd find a way in.”

“I tell TAMMY it will be all right. She says what will be all right? I say whatever you are crying about. She says that is exactly what she's crying about. That everything is all right. That the world isn't ending. That we'll never tell each other how we really feel because everything is okay. Okay enough to just sit around, being okay.”
