Sorry, long post!
Okay, I share an apartment with two girls and the one's boyfriend who basically lives there, all three of which are typical college "lets party!!!" people (assigned living sucks!). Everyone else has their own bathroom, except me. I have the "shared bathroom" which connects to the kitchen. They have agreed not to use it, but I think that they sometimes do. Oh, and there is no way to lock it from the outside
I came home today to find the toilet seat up. It could have been anything from the boyfriend just had to pee while his girlfriend was in the shower to someone couldn't make it upstairs to their bathroom to throw up. (and the one girl gets sick a LOT)
Everything else is the same way I left it, not trace of V anywhere, no one has cleaned it since I last did. My boyfriend assures me that if they were in that much of a rush, they would have made some mess. I'm not freaking out about it, but, once again, I am very uncomfortable in my own house. Neither girl has any common sense in their heads and the one got three stomach bugs in three months (personally, I think that she doesn't know a thing about food safety and gave herself food poisoning), and she loves getting wasted. The other has thankfully been healthy. Due to terrible sound proofing, I can hear EVERYTHING that happens in her bathroom, so thank god shes the healthy one! I can't move out, and they'll charge me over $200 to change to a different room which isn't guaranteed to be any better.
Advice?
