After observing teens and their parents for the last 20 years as a teacher, here's what it's all about (and I apologize up front for all you who have already figured this out):
1) Parents who have an active, caring role in their kid's lives will mostly produce kids who are well adjusted, regardless of what violence the kids are exposed to.
2) The % of parents who have an active, caring role in their kid's lives becomes less and less every year.
It's sad but true ...
There's no place like 127.0.0.1
