we have the same problem

I have the same problem with my girl, what I am doing now is relaxing but at same time, monitor her behavior and try to be her friend, don't see no too quick and crticize her when she ask something, try to listen and understand her from her point of view, find a good time to talk when there is something very serious, I know it is tough, but she still knows that we love her, and nobody else will love and care her like her parents, try to trust her and encourge her to be honest,tell her even if she did somthing wrong, we will deal with it together, don't need to lie, everybody made mistakes. it seems working but we are still learning how to improve, it is such a tough job to be a rebelly teenager's parent, especially girl. Good luck for you all!
