“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.)”

“For a long time, all the way through to the end of elementary school, Beans was my only friend. Because that’s how I’ve always been. I only need one good friend to see me through. Most people aren’t like that. Most people are always looking out for more people to know. In the end, Beans was like most people. After a while she had dozens of friends, and by fifth grade it was pretty obvious that even though she was my best friend, I wasn’t hers.”

“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.”

“As the elevator door started to close, she stood and put up one hand to wave goodbye. That’s one of those frozen memories for me, because there was something in Greta’s solemn wave that made me understand it was about something bigger. That as the elevator door eclipsed the look between us, we were really saying goodbye to the girls we used to be. Girls who knew how to play invisible mermaids, who could run through dark aisles, pretending to save the world.”

“I didn’t say anything. Greta always knew how to make me lose my words.”

“It was a nice thing for her to say. In her way. With Greta you have to look out for the nice things buried in the rest of her mean stuff. Greta’s talk is like a geode. Ugly as anything on the outside and for the most part the same on the inside, but every once in a while there’s something that shines through.”

“My mother gave me a disappointed look. Then I gave her one back. Mine was for everything, not just the sandwich.”
