I don't like pictures, paintings etc on walls being even slightly off.
I've got friends who have a painting that's above their fireplace and it's off by quite a distance (ok probably about 3mm) but it fucking annoys me cos the frame is screwed to the wall rather than hanging from a hook - so it's not possible to just adjust it while they're out of the room.

My GF likes the TV volume to be on an even number.
My sister is proper OCD though - after we've had dinner all of the chairs must be placed in exactly the right place so that they sit in the existing dents in the carpet. Whenever she's out of the room I move one just for a laugh. I'm a prick.

I went to my ex-bosses housewarming party many years ago
He had his CDs in perfect alphabetical order and drinks coasters everywhere. We spent an hour swapping all the CDs around in the cases
