13 year old daughter seems to not care about anything at all. we have grounded her according to John's book, we have done "tickets", she is extremely moody, mean and nasty to family and calls her parents "idiots, jerks" etc. She is disrespectful and honestly does not seem to care about any consequences at all. She often can not do anything with friends on weekends because of her behavior, but that does not seem to motivate her at all to do better. She will not stop homework (we try to follow John's book on success in school) and if we tried to take her computer away she screams and hits us and fights. She doesn't seem to mind being grounded according to John's book.
