This is typical of kids in this situation. You all need to be on the same page about house rules first. You allsit down and discuss them, adjusting things until everyone agrees on what's fair. Then, you need to spell out the consequences for breaking each rule and do the same thing-- negotiate what's fair. Once everyone agrees, ther's no conflict. You break the rule, you get the consequence, period. We raised 5 teenagers, and this saved a TON of aggravation. A hint from a family therapist--- don't take things away as punishment if you can help it, because a teenager will not care, just to get to you. You give them extra chores, like cleaning toilets, washing cars, vacuuming, etc.---all negotiated and agreed to , of course.
