“I don’t have many friends. TAMMY, I guess. Her soul is code, is a fixed set of instructions, and although you might think having a relationship with someone like that would get boring after a while, it doesn’t. TAMMY’s AI is good. Really good. She’s smarter than I am, by a mile, by an order of magnitude. In all the time I’ve known her, TAMMY’s never said the same thing to me twice, which is more than you can ask from most human friends. Plus, I have Ed for petting and body heat. I think that probably sounds more yucky than it really is.”

“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.”

“For the past several years, I have gone to sleep every night in this same little pocket, the most uneventful piece of time I could find. Same exact thing every night, night after night. Total silence. Absolutely nothing. That's why I chose it. I know for a fact nothing bad can happen to me in here.”

“How many times have I failed before? How many times have I stood here like this, in front of my own image, in front of my own person, trying to convince him not to be scared, to go on, to get out of this rut? How many times before I finally convince myself, how many private, erasable deaths will I need to die, how may self-murders is it going to take, how many times will I have to destroy myself before I learn, before I understand?”

“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.”
