This is the tragedy of modernity: as with neurotically overprotective parents, those trying to help are often hurting us the most.
My parents were overprotective because you could get kidnapped and bombs were exploding in the streets.
I think parents generally know what's best for their children. But I suppose it's possible to be overprotective.
Now that I have kids, I'm probably more overprotective than I've ever been. My wife's nickname for me is 'red alert.' I sometimes check just to see if the kids are breathing. But I try not to be a helicopter parent.
Parents don't know their children at all.No one knows anyone, in fact.
