“Opening a present from a live person was scary enough. There was always the chance that the gift might be so wrong, so completely not the kind of thing you liked, that you'd realize they didn't really know you at all.”

“I really wondered why people were always doing what they didn't like doing. It seemed like life was a sort of narrowing tunnel. Right when you were born, the tunnel was huge. You could be anything. Then, like, the absolute second after you were born, the tunnel narrowed down to about half that size. You were a boy, and already it was certain you wouldn't be a mother and it was likely you wouldn't become a manicurist or a kindergarten teacher. Then you started to grow up and everything you did closed the tunnel in some more. You broke your arm climbing a tree and you ruled out being a baseball pitcher. You failed every math test you ever took and you canceled any hope of being a scientist. Like that. On and on through the years until you were stuck. You'd become a baker or a librarian or a bartender. Or an accountant. And there you were. I figured that on the day you died, the tunnel would be so narrow, you'd have squeezed yourself in with so many choices, that you just got squashed.”

“The walls of the tunnels were covered with so much dirt, it was almost like fur. I thought those tunnels were the kind of places wolves might live. I thought they were like the vessels of the human heart.”

“That's the secret. If you always make sure you're exactly the person you hoped to be, if you always make sure you know only the very best people, then you won't care if you die tomorrow.”

“I came to a sketch where the space between my arm and Greta’s arm, the shape of the place between us, had been darkened in. The negative space. That’s what Finn called it. He was always trying to get me to understand negative space. And I did. I could understand what he was saying, but it didn’t come naturally to me. I had to be reminded to look for it. To see the stuff that’s there but not there. In this sketch, Finn had colored in the negative space, and I saw that it made a shape that looked like a dog’s head. Or, no—of course, it was a wolf’s head, tilted up, mouth open and howling. It wasn’t obvious or anything. Negative space was kind of like constellations. The kind of thing that had to be brought to your attention. But the way Finn did it was so skillful. It was all in the way Greta’s sleeve draped and the way my shoulder angled in. So perfect. It was almost painful to look at that negative space, because it was so smart. So exactly the kind of thing Finn would think of. I touched my finger to the rough pencil lines, and I wished I could let Finn know that I saw what he’d done. That I knew he’d put that secret animal right between Greta and me.”

“I’m not a violent person. I didn’t think I was a violent person, but right then something dangerous seemed to be waking up. Some hard dark sleeping thing from deep in my belly had opened one eye.”

“The day my mother gave us the keys, she also made me and Greta sign a form so that the bank knew our signatures. To get in we had to show our key and sign something so they would know it was really us. I was worried that my signature wouldn't look the same. I wasn't sure when that thing would happen that made it so you always signed your name exactly the same, but it hadn't happened to me yet. So far I'd only had to sign something three times. Once for a code of conduct for the eighth grade field trip to Philadelphia, once for a pact I made with Beans and Frances Wykoski in fifth grade that we'd never have boyfriends until high school. (Of the three of us, I'm the only one who kept that pact.)”
