I can't tell you if I'm Riley Anderson, but I do have Riley's memories. I remember squabbling with Amy over the blue dolphin eraser when we could barely walk. I remember sorting, labeling, and binding my fresh notebook paper before every school year. I remember sacrificing the same eraser, now broken, and the same paper, now used, to my graduation bonfire. And I remember learning that my lymphatic cells had stopped working so they could eat, drink, and be merry.
