My 20 year old daughter does not communicate well with us. She says we think she is an idiot. She was raised in a functional, Christian home, and is a third year college student with no major. when we try to talk to her about college grades and majors, she becomes irrational and has outbursts of unkind remarks toward us, her parents. what have we done wrong, and what can we do to change her attitude. She is very pretty.
