A few years ago, my daughters and I were searching for sand crabs on a white-sand beach near Monterey. A group of sixth graders descended on us, clad in the blue trousers and pressed white shirts of their parochial school. Once lost in the sounds of the surf, away from their teacher’s gaze, they called one another by nicknames and mocked the way one laughed, another walked. Noogies and rib pokes, headlocks and bear hugs caught the unsuspecting off guard. Two boys dangled a girl over the waves. Three girls tugged a boy’s sagging pants down. Dog piles broke out. In a surprise attack, one girl nearly dropped a dead crab down a boy’s pants.
As they departed in sex-segregated lines, my daughters stood transfixed. Serafina asked me, “Why did that girl try to put the crab in the boy’s pants?” “Because she likes him,” I responded. This was an explanation Serafina and her older sister, Natalie, only partly understood. What I witnessed might be called “the teasing gap.”
