Most of our old family photos are from the beach, and most of them are of my father. In them, he is always grinning, gleaming from the Hawaiian Tropic suntan oil that scented the denim shirt he wore every summer. My mother loved the beach, too, but did not like to be photographed. In all those years, Dad caught Mom on camera only once, on a boogie board riding a wave, still wearing the sunglasses that stayed on her head all summer, even after dark. She preferred to float, read, and take pictures of my brothers and me. Blindingly pale or perilously pink, like “before” ads for skin cancer, we’re inevitably chewing or punching or blinking, ruining the picture. My father, however, always looks perfect, natural, exactly where he’s supposed to be. His hands are on his hips, superhero-style, as if he’s won some high-stakes game and the beach now belongs to him.
