This question is not about my children (I don't have any) but my 16-year-old brother. Sometimes he is the nicest kid in the world, but now he is acting out and not listening to my parents. My parents are fighting about it and not getting along and I have another brother and sister who are younger and cry because C___ and mom are fighting. He does not listen and is starting to fail school. He just got his license and thinks he is invincible. My mom calls me crying all the time about it and I don't know what to do. Help!!
