There is such a thing as "house rules" and parental respect.
If she doesn't want to obey house rules (no sex in our house, let us know where she is going and when to expect her return, etc) then she can move out. She has already played that threat. I told her "go ahead".
I'm used to all of the girls dis'n me. However, when they start on their own mom, that's too far. They can make those statements from their own residence, not ours.
