My 13 year old thinks he has a right to walk out of the house and leave (to the park, friends house, who knows) whenever he gets upset, is getting scoldings (yup, right in the middle of it), etc. He has an attitude problem ( I thought only girls get like this as teens), and he's been acting up so bad lately, that this time, I just lost it..and let him hear it. I yelled and screamed and told him how disrespectful he was being and has been, and how he thinks he can just act like this and get away with it, how I'm sick and tired of it...etc. Well, he walked out of the house.....AGAIN. I don't know where he went. I'm so upset, I just want to lock him out and leave...but most of all I just want him home where I know he's safe. How do I deal with this behavior? How do I discipline this?
