“The red indicator light just came on. I'm looking at the run-time error report. It's like a mathematically precise way of saying, This is not how you do this, man. Meaning life, I suppose. It's computer for Hey, buddy, you are massively bungling this up. I know it. I know it better than anyone. I don't need silicon wafers with a slightly neurotic interface to tell me that.”

“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.”

“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.”

“I don't miss him anymore. Most of the time, anyway. I want to. I wish I could but unfortunately, it's true: time does heal. It will do so whether you like it or not, and there's nothing anyone can do about it. If you're not careful, time will take away everything that ever hurt you, everything you have lost, and replace it with knowledge. Time is a machine: it will convert your pain into experience... It will force you to move on and you will not have a choice in the matter.”

“For a while, I thought I might be in a love story, but I hardly ever wake up next to anyone anymore. It still happens once in a while. When it does, the first thing I do, doesn't matter where I am, in the ocean, on the moon of some minor distant planet, doesn't matter where, doesn't matter if she knows who I am of if I know who she is or how strong gravity is or if I feel terrible or if the world is logically impossible, the first thing I do if she's there, is I tell her how nice it is to see her.”

“There is a sense in which I am pretty sure this makes no sense. I don't know where this is going. I don't know how it ends.”

“When it happens, this is what happens: I shoot myself.Not, you know, my self self. I shoot my future self. He steps out of a time machine, introduces himself as Charles Yu. What else am I supposed to do? I kill him. I kill my own future.”
