.....ok ....well thats YOUR kid . and congratz on having a kid that actually gives a damn about etiquette , the Social Contract, and manners. Thanks for raising them like so.
HOWEVER most of the kids Ive encountered have gone out of their way to disobey the Social COntract. And Im not talkinng toddlers Im talking kids who are probably in high school. So kids that were clearly old enough to understamd that there is a time and place to be loud, party, and destructive and a time and place to not be.
