I am a key. Not the key that turns a common lock, but the key that opens the drawer where photographs sleep. You use me in the slow ritual of turning tumblers — a quarter turn, another — and the smell of dust and vanilla rises like a memory. Dainty keys fit small locks on travel trunks; wilder keys are jagged, worn by hands that have wandered. Exclusive: a single key opens a chosen cabinet, a confidante kept inside: letters tied with twine, a concert ticket, a pressed moth wing. When you use me, you admit a past into the light.
