That one is awesome! It really makes me look back at the days when I had roommates, and NOT MISS THEM AT ALL! *snickers*
I like this one, especially cause it's something that pretty much anyone that's had a crappy roommate, or had to share a bathroom for some reason, can really get a kick out of. It relates to a lot of people, if that makes sense? Plus, the bathroom is a really private place for a lot of people...we do our "dirty work" in there, as well as making ourselves up for the day before other people can see us. Having someone else invade that space, and then mess it up without thought to another person's feelings, is really intrusive and sometimes rude...
Hehe, anyway, I liked it.
