She was folding someone else's forgotten sock when the machine behind her stopped.
It was half past ten in a launderette on a side street, the kind of place that keeps the lights on for anyone who needs them. Three machines were running, but only she was there. The fluorescent strip above the change machine had been flickering since she arrived, and she'd stopped noticing it the way you stop noticing a dripping tap.
The sock was grey, crew-length, with a small hole worn through the heel. She folded it anyway and placed it on the lost-property shelf — a plank above the radiator, holding a child's glove, a belt, and a paperback with its cover torn off. She felt, obscurely, that someone would come back for it.
