and while he still lives in his parents' house, he is subject to their rules.
All the bad behavior needed to be punished. The lying, the drinking, the rampage, the staying out too late, etc.
This is no different than my taking away a toy gun from my son for his misbehaving with it and selling it at a garage sale.
What would you do, send the kid to his room so he can play on the PS2 for hours? This way he learns a lesson.
Ah for the good old days when spanking was a solution for every discipline problem. Get a big old paddle with holes in it and hit really hard. If the behavior repeats, hit harder. Schools used to do this as well and didn't have the discipline problems they have today. Oh well, let's just spoil the kid and give him even more games to play with. Send him to his room so he can play some more. Ground him to stay at home, where his PS2 is. Yeah, that'll teach him. Maybe he can find the time to finish GTA3 for his punishment? ;)
