I found a set of shark teeth as big as my palm and sneaked up behind him, then pretended to bite his hip. He spun, letting loose a high-pitched gasp as he flushed Harvard crimson. I howled, laughing so hard he tried to push me away, but I got my arm around his waist and held up those shark teeth, moving them like chattering, wind-up dentures. He caught my giggles, and we both turned into each other, too wound up in the hysterics to notice how we were inside each other’s space, our arms and hands and thighs together like we were hugging, or like we were doing more than hugging.
