it went down the same way with me. except i had to re-write it around a 100 times to meet my counselor's liking untill he found it acceptable enough to even be shown and considered by my parents.
the problem of tension, which you ignore and cant see, is that it forces the parent to be a cop, and enforcer of the laws set by the contract. The tension within the family has a direct relationship with the amount of enforcement the contract gets, and how much the kid resists.
The problem of resistance is ever present among anyone with any sense of dignity. once a kid leaves their program (weather pulled or graduated, doesnt matter as long as they were there long enough to get affected by it) they start the process of realizing how much the program really messed with their head. depending on the circumstances, that process can be long or short. for me it took less than 24 hours.
a good illustration, though somewhat exaggerated by current program standards, can be seen in the movie OVER THE GW. i highly recommend you watch it.
