Do these roommates start out as "friends" or someone you happened to "luck into"?
Either way, I think that everyone should sign a contract AT THE BEGINNING that says something to the effect of " if my sig. other spends more than 1 week every night in this place, then I will be REQUIRED to pay extra in rent". If I fail to do this, the landlord will be told so that legal action can be taken against the person breaking the lease.
If I am paying my agreed-to portion, why should I have to put up with someone who is not? and/or doesn't follow "normal" common courtsey????
Does anyone discuss how to handle problems that may exist BEFORE the lease is signed???
((To OTHERS IN IHEARTMATT'S SITUATION,, why not create a flyer to know your roomie that you wil be opening the apt/dorm. door the next time they are having sex to let the public in to watch
