Obviously this would depend on the level of conflict, but if we're talking about the kind of conflict normal parents have with relatively normal teenagers, this is nothing to get excited about in the long term.

Conflict and pushing the parental envelope is the norm for teens, and so it should be, up to a point.

Bear in mind who the adult is, and while you as a parent may be pissed off, try and keep it in context.

I know a couple who doted on their two children. One turned out fine and the other is a grasping, ungrateful bum. The anguish is heart-rending to watch as the parents try to cope with the problem.
