What sort of consequenses are appropriate for a 17 yr old?

i honestly have no idea what to say...maybe see needs to go to some sort of exchange program where she has to live where she doesnt have all the good things she has at home. this might seem kind of wierd but i recommend you watch a show on MTV called exiled. its pretty much about all the "sweet 16 brats" that their parents are fed up with their attitudes and running up their credit card bills and other things that they send them to other parts of the world to give them a week of real work and to show that they have something good and shouldnt take it for granted.... but it also seems like you need to start to try to control her as well shes walkin all over you...and thats not right for her to do.
