re: OT parents: kids dating innapropriate partners

Too much ambiguity in OP. Is this socioeconomic. Is this ethnic? Is this just appearance-related?

GFunk's sis was a black sheep...and even though she ended up with a black sheep husband, they've managed to reproduce two amazingly wonderful young kids who are somehow unspoiled by their parents knuckleheadedness.

I learned a long time ago that my parents trying to come down on her with an iron first just made her want the people and decisions they were preventing her from even more. Even though it would've been the best for her and even though she sees it now on the backside of her 30's.

No kids on my end but most of us have seen this happen with a friend, a sibling, or a child of our own. The best way to do things is just chill and/or steer into the skid.

Or boarding school. Boarding school is always an option.
