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

“I wasn’t trying to invent better and better homes, but to show her that homes didn’t matter, we could live in any home, in any city, in any country, in any century, and be happy, as if the world were just what we lived in.”

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

“Are you an optimist or a pessimist?" "I can't remember. Which?" "Do you know what those words mean?" "Not really." "An optimist is positive and hopeful. A pessimist is negative and cynical." "I'm an optimist." "Well, that's good, because there’s no irrefutable evidence. There’s nothing that could convince someone who doesn’t want to be convinced. But there is an abundance of clues that would give the wanting believer something to hold on to.”

“What if I never stop inventing?”

“I said, 'I need to know how he died.'He flipped back and pointed at, 'Why?'So I can stop inventing how he died. I'm always inventing.”

“We tried so hard. We were always trying to help each other. But not because we were helpless. He needed to get things for me, just as I needed to get things for him. It gave us purpose. Sometimes I would ask him for something that I did not even want, just to let him get it for me. We spent our days trying to help each other help each other. I would get his slippers. He would make my tea. I would turn up the heat so he could turn up the air conditioner so I could turn up the heat.”
