I NEED help with TEENAGERS?

Well what I would do is try to get them to sit down with you and tell them that you were wrong to go off on them like you did but with that being said it it very ugly to be doing what they are doing in front of people. You probably wont be able to get them to stop because they are teenagers but you might be able to talk them into just doing it in private. Tell Brandon that you see him as a little brother and you don't want people thinking that he isn't a good guy, and doing the things he is doing makes him look bad. The same for Abby tell her that you were upset and calling her a slut was a bit much but that it does look bad even if they don't mean anything buy it. Teenagers do not respond to yelling and criticizing but if you tell them you know where they are coming from and that they can keep being with each other just act normal around friends and family it might work. If they wont talk to you try getting Alex to relay some of the message so they will talk and you can tell them the rest in person
