UGH ungrateful people.... and know it alls

So get this Brittany and Don are up at my neighbors! they took my food up) ... People are telling me I am being to nice letting don stay on the way I am... So I text brittany and tell her they better change their way and respect me in MY home or I am changing their move out date! She tells me I can't do that.... breech of contract! ( no doubt she got that from bill) I tell her there is nothing in writing! she comes back "verbal" I tell her he is NOT paying rent that he is squatting, so i can ask him to leave any time... she writes nothing back about that.. She is going on and on asking how they are being rude, I told her that this is one way ( the texs) and then she tells me I am being just as rude to him (don) as he is me! UMMMM hellooooo ME grown up, MY house, my rules.... don't like it get the F out!!!!! I turned off my cell I was sick of the texes!!! I told her she better call her dad and take him up on that room at his place! I have had it!!!! She is saying stuff like how don does this and that and takes me here and there and that should be "thanks" enough.... HELLOOOOOOO????? he still has not spoken to me now going on 10 days! she tells me that it works both ways!!!! Their dishes are still sitting in the sink from monday!!!! And I am paying her cell... She has no idea how lucky she is...
