Don’t overlook the effect of drug use. The expotential rise of habitual drug use over the past sixty years correlates with the decline of the American family ( divorce, estrangement, early deaths etc).
Including doctor prescribed drugs, particularly pain drugs.
When you're a drunk, you do some pretty ugly things, especially to family.
My father's last words to me were "Don't call me, don't write me, don't even THINK about me."
Sober for thirteen years and he still won't speak with me because of the crap I pulled.
My daughter is wonderful. Lives 40 miles away, has a great husband and home, votes Republican. Handles money very well and like others in Idaho, didn’t get vax and never wore masks. My son, always the smartest and best-looking person in the family, walked out of a 250K job to drink, always tries to tell me what to do. Thinks my affairs need to be handled by someone else because I don’t want vax. I love him but I can’t stand him. He’s a jerk.
