My H and I spent the first 18 years of my son’s life giving him the tools necessary to become a fully functioning independent adult. IMO, that is what parents should be teaching their kids to do. Anyway, it has worked incredibly well.
He also knows he can always come to us for advice, but we never give our opinion without him asking or interfere in decisions he makes. He recently switched jobs and we didn’t know he was even looking. Found out after he had accepted his new position, left his old job and was about to start new one in two weeks.
