I'd be slightly less annoyed at my roommate for writing a passive-aggressive "please dear god clean the bathroom" letter instead of coming to me herself if she could tell the difference between my hair and hers. It's really freakin' easy. I'll give you a hint: mine is fine, light-colored, and relatively straight, while hers is thick, black and kinky. If I can tell the difference when I'm halfway across the bathroom, why can't she? I realize that my hair is always going to be everywhere (at some point, all of my possessions have had or will have hair on them - not just my clothing), but it's not the ONLY hair there. WTF?
At least now she can't complain that the bathroom is dirty.
