annoyed

My father in law and mother in law split, he kicked her and her sister out, so my husband and I decided that they can temporarily stay with us until they find their own place. His mom was approved for a house but she made him call and talk to the people who are loaning her the money and the realtor, which is very time consuming, I just bought a house in May. They don't help pay for anything and constantly leave the lights on. I wouldn't care if it's just one but they leave all of them on. My husband has talked to them about it but they still do. They don't buy their own food so we went from feeding us two, to four people. They don't buy their own laundry detergent and expect us to buy it, and they use ALOT. I don't expect them to pay for everything but something would be nice since we have a baby on the way. His aunts has a friend from a different state come to visit and staying in our house without asking, and they have been going to out to dinner and she's paying for everything, she can pay for the meals but can't help us out a little. And they will be here for at least another month. I hope I have enough patience...
