I leave Nan and Charlie to make the salad, and when I return to the living room, he’s sitting on a dining chair in front of her, painting her nails with the purple polish. He’s doing a terrible job, the tiny bottle cap ill fitted to his hands. I sneak past to get my camera. I take one shot of Charlie concentrating on Nan’s manicure, her fingers in his, and another when they both look up at me.
