Personally, I think public bathrooms are gross. You'd think women wouldn't PEE ALL OVER THE SEAT, but you'd be wrong. Ulgh. Don't get me started on the library bathrooms, which were HORRIFIC.

Also, the bathrooms at Pentagon City Mall in Virginia. Really. Very. Putrid.

I don't especially enjoy using the facilities at a friend's place, but at least it's bound to be cleaner than a public bathroom...
