My place is nice and clean but that's entirely in spite of me, not because of me. If people didn't clean up after me it would be phenomenally scruffy and I wouldn't care less about it. I could go years without bothering to clean anything. Decades possibly. Luckily I've never had to find out how long I'd actually go before cleaning up after myself but I'm sure I'd be world class in terms of potential scruffiness.
