I stood on the porch of 58 Chestnut Street at 11:47 PM on a Tuesday in late October, a key I didn't remember making in my hand, the doormat flipped back by the wind. The porch light was off, but a television flickered blue through the living room window — the shape of a woman on the couch, her head turned toward the driveway. I knew the house was supposed to be empty, but the woman was me — same hair, same posture, same sweater I'd lost at a laundromat last spring. When I unlocked the door, the television went silent, and I heard a voice from the kitchen ask if I wanted tea. I'd never been inside, but I knew where the mugs were. I knew the crack in the sugar bowl. I knew the name of the dog that had died two years before I was born. The woman on the couch never turned around, but she said my name — the full one, the one only my grandmother used. I left the key in the lock and walked backward down the driveway, and when I got to the street, the porch light clicked on.
