My parents were the same way... I didn't really have a problem with it, cause I wasn't a 'bad kid', and wasn't doing anything wrong, so I didn't have anything to worry about... (lets not start that infringing on freedoms discussion... lol... they are parents, not uncle sam)...
I am at a point where I am Adult, but not a parent, and yet still young enough to have the teenage mentality...... Ok, I'm 25, but don't really feel that way.... My brother & sister are 6 & 8 year younger than me. They both still live at home, and my brother I would think is similar to you revenge2... (not saying you are like this, but this is how he is)... He has a problem with the fact that he is 19, and has no more 'legal curfew', but my parents still give him a curfew. I find it really funny that he can't understand the fact that it doesn't have so much to do with them trying to ruin all his fun, as it does with the fact that he wakes everyone up when he comes home, or will bring people over late. The way I see it, if you live at home past 18, your parents are your landlords, and you must follow the rules they put in place. If you don't like the rules, your options are to 1, talk with them about the rules, and possible changes, 2, move out.
Looking back, I would have to say that when we argued, my parents were right about 90-95% of the time. I didn't really argue with my parents much when I was a kid.... I was under the 'roll with the punches, play the game' mentality.... I dunno....
Wow, just zoned out for a few minutes at work and typed that... almost time to go, YAY!.
