I've seen some stellar parents that had trainwreck kids and I've seen (while growing up) parents that were worse than a trainwreck who's kids turned out rock solid. There was this one case where the parents literally didn't care what the kids did (there were 3) and every Friday, Saturday night and Sunday it was a free-for-all. Everyone expected the kids to turn out the worst. Crazy thing was all three kids ended up going to college, getting great jobs with two of them becoming wealthy. You just never know.
