Wow then the girls at UCSB must have been a rare breed of slob. Almost all of the guys I knew might have had a few days worth of clothes strewn about the room. But, girls on the other hand had makeup, soda bottles, food, clothes, ashtrays and God knows what all over, not to mention a sink full of 2 weeks worth of dirty dishes.
Well you did go to school in a state overpopulated with hippies and hoodlums!
Seriously though, I guess it just comes down to luck of the draw. Still - and i'm sure you'd differ on this point - there's nothing that ruins my day more than a guy walking around in his underwear with his ass crack showing, and we had a couple of those types living with us at times.
