She is rude, disrespectful and generally not a nice person.
She asked to stay over a friend's house tomorrow night. No was the answer. After much whying and whining I told to accept it was a no. What came back was "actually, I'm just letting you know, not asking your approval."
That level of rudeness side swiped me a bit and I told her that she wasn't grown and she wasn't able to make those decisions.
Her response "I wasn't talking to you, I was talking to dad, you mean nothing to me!"
Poor dd(11) burst out crying and told her how horrible she was.
Unfortunately, I lost my temper at that point and bawled at her.
My dh and I have absolutely no idea how to deal with her.
Her disgusting attitude has been building for about 6 months. I am at the end of my tether.
