How about less “control everyone else” and more “control your own damn kids”.
My daughter didn’t get unsupervised access until she proved responsible enough to trust. I want to say around 13.
Just because “I grew up with it unsupervised and it ruined me” doesn’t immediately equal “everyone will have this experience”. Sorry your parents didn’t understand what you were doing. Sorry you saw stuff that bothered you. Don’t punish everyone else for it.
I’m far from a helicopter parent… Instead, my kid has come to me for help in resolving uncomfortable or problematic interactions. We’ve always been clear and honest about why we’ve asked her to avoid certain things. Even when it made us uncomfortable. Especially then.
She’s 20 now. Most cheerful kid I’ve ever met. No idea how that happened directly, but I know I can trust her.
