I don't want to pry into your personal biz, but u mentioned that dad left. Is he not even present in your sons lives? When you say left do you mean he skipped out or passed on? Sorry, if its to personal, please don't feel that you have to answer. About the garage, does your son use it as his room and that's why he gets so crazy about it. If not all i can say is that its your house, should be your rules. If he wants to act like a jerk about it, out your foot down. I can somewhat relate to hin though. I was rebellious and I tried to take hold over things that were not rightfully mine. As soon as someone talked (screamed) some sense into me I calmed down. Sorry you have to go through this, I imagine it must be tough. I wish you well and God bless you.
