I am so sorry you had to go through what you did. They would not be invited back and if BF didn't like it, he could go too. I agree, get some kind of lock for the door and only you have the key. Obviously, the mother has no respect for anyone else since she laughed about it. Her kids are brats and will someday probably all in be in jail. Actually, I kind of like the suggestion about the special brownies in Lostin 50 suggested!!! It would serve them right.
