I know exactly what your going through. The only difference is I have a 12 almost 13 year old son. He is the same way. Very disrespectful!! It angers me and it causes major wars in our household. Right now, I try to just avoid communicating with him unless it is absolutely necessary. I let him come to me when and if he needs anything. It seems to be getting a little better, but who knows. I also try to pick my battles, I think to myself, "Is this worth the fight?" If not, I won't even go there. Good Luck, I have a feeling we are both gonna need it!!
