History Lesson

I am four in this photograph, standing on a wide strip of Mississippi beach, my hands on the flowered hips of a bright bikini. My toes dig in, curl around wet sand. The sun cuts the rippling Gulf in flashes with each tidal rush. Minnows dart at my feet glinting like switchblades. I am alone except for my grandmother, other side of the camera, telling me how to pose. It is 1970, two years after they opened the rest of this beach to us, forty years since the photograph where she stood on a narrow plot of sand marked colored, smiling, her hands on the flowered hips of a cotton meal-sack dress.
