LOL! Ah. Me too. Before I leave in the morning, even if I'm running late, I'll compulsively wash the dishes. Or wipe a counter. The idea of leaving food out on dirty dishes makes my skin crawl. Remember when I was in undergrad sharing a house with ten other people - we shared a kitchen.
And they always left the dishes in the sink, never cleaning. Three of us took turns doing it, because it drove us bonkers. Same with vaccuming.

I don't like messes, I suppose. I feel an urge to step in and clean them up. Which may be why I'm good at my job - constantly cleaning up messes.
