I’m genuinely very sorry for your loss. A parent should never have to outlive their children. There certainly are exceptions however the overwhelming majority of good responsible children come from good responsible parents and vise versa. My wife is a special ed (behavior specialist) teacher and over decades of involvement with her classes I can tell you for a fact that is the case.That's very interesting. My wife and I don't smoke, drink, gamble. Raised our kids in church and Scouts and led by example.
I go visit my oldest son's grave every weekend. He did drugs, got hooked, spiraled right down and was gone at age 24. He was the apple of my eye.
I guess if you do stuff right, and you get lucky - it's easy to give yourself credit for your kids choices. If you see other kids doing bad stuff, it must be very gratifying to smugly blame the parents.
