right. you warn them, then when they get in trouble you say "guess you should have listened better huh?". That is how ANYTHING learns. by seeing terrible behavior rewarded terribly. Not by having every fucking jam you DO manage to get into bailed out by mommy and daddy.

i think what these parents fail to grasp is that it's how your kids behave when you AREN'T there to watch out for them that is important. Because that is how they will behave into their adult lives. You need to give them those opportunities to act on their own, fuck up, correct the behavior, and persevere or they will never ever gain the skill to do that.
