Nasty Roommate!

OK I really do have wonderful roommates. I only have uno problem. The roommie I share the bathroom with is sooo nasty! I mean by the time it's my turn to clean the bathroom, there's mold on the sides of the bathtub even though I spray that shower stuff everytime I take a shower. I have never seen her clean the bathroom ever but I am an extremely busy person and the only time I'm in the apartment is to sleep and eat so I could've missed that. I don't know. Oh well, that's my vent for the nite!
