“Being with him made my brain quiet. I didn't have to invent a thing.”

“I loved having a dad who was smarter than the New York Times, and I loved how my cheek could feel the hairs on his chest through his T-shirt, and how he always smelled like shaving, even at the end of the day. Being with him made my brain quiet. I didn't have to invent a thing.”

“I started inventing things, and then I couldn't stop, like beavers, which I know about. People think they cut down trees so they can build dams, but in reality it's because their teeth never stop growing, and if they didn't constantly file them down by cutting through all of those trees, their teeth would start to grow into their own faces, which would kill them. That's how my brain was.”

“I think about all of the things I've done, Oskar. And all of the things I didn't do. The mistakes I've made are dead to me. But I can't take back the things I never did.”

“I tried to think about other things. I tried to invent optimistic inventions. But the pessimistic ones were extremely loud.”

“I tried the key in all the doors, even though he said he didn't recognize it. It's not that I didn't trust him, becuase I did. It's that at the end of my search I wanted to be able to say: I don't know how I could have tried harder.”

“A lot of the time I'd get that feeling like I was in the middle of a huge black ocean, or in deep space, but not in the fascinating way. It's just that everything was incredibly far away from me. It was worst at night. I started inventing things, and then I couldn't stop, like beavers, which I know about. People think they cut down trees so they can build dams, but in reality it's because their teeth never stop growing, and if they didn't constantly file them down by cutting through all of those trees, their teeth would start to grow into their own faces, which would kill them. That's how my brain was.”
