“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.”
