Christ. Parents, present and future:
Talk to your children. Love your children (and tell them). Be present for your children. Listen to your children. Be fucking nice to your children. Have expectations for your children and raise them to know there are expectations, and teach them to see expectations and challenge as positives. Spend time with your children, from day 1 and as much as they will let you. And get your children the help they need. If you don't, someone else will give them a "reason" in their teens/later to spiral downward and find an easy "home" with lunacy and lunatics.
