Some authority on parenting once said, ""Hold them very close and then let them go."" This is the hardest truth for a father to learn: that his children are continuously growing up and moving away from him (until, of course, they move back in).
I am certainly not an authority on love because there are no authorities on love, just those who've had luck with it and those who haven't.
You can never give complete authority and overall power to anyone until trust can be proven.
