Apparently, my mother hadn’t spoken to my father for a week after he’d taken his eye off me and I’d careered into the pool. “But you came up, doggy paddle in full motion, and that was it—from then on you could swim. With the other boys, they all had pool noodles and arm bands and swimming lessons. But not you. You just swam. From six months, that was it. But that’s you, Nathan.”
