I spent the rest of the school day on the flat hard green carpet of the classroom library reading picture books about animals getting into fixes. A splinteringly dry afternoon. Eddie and Eliza came over with curious eyes to see if I wanted to play four square or dodgeball after school, but I told them I wasn’t feeling well. You don’t want to get this, I said, coughing a little in their faces. I dragged my feet to the bus. At the stop, Joseph looked wrung out from the day too and took his usual spot right up against the window, but this time he sat with a friend, a guy with high arched eyebrows and rangy arms and legs. They hunched over a textbook and talked and pointed the whole ride home.

It was Wednesday, and George always came over on Wednesdays after school. He was Joseph’s best and only friend. George Malcolm: half white, half black, with messy tousled hair, rumpled and tugged between kind of curly and extremely curly. Once, a year or so before, he’d been at our house and he’d pulled out a lock of his hair and used it to teach me about eddies and helixes. It’s a circular current into a central station, he’d explained, giving me one to hold. I pulled on the spring. Nature is full of the same shapes, he said, taking me to the bathroom sink and spinning on the tap and pointing out the way the water swirled down the drain. Taking me to the bookshelf and flipping open a book on weather and showing me a cyclone. Then a spiral galaxy. Pulling me back to the bathroom sink, to my glass jar of collected seashells, and pointing out the same curl in a miniature conch. See? he said, holding the seashell up to his hair. Yes! I clapped. His eyes were warm with teaching pleasure. It’s galactic hair, he said, smiling.
