My parents were so deathly afraid of peer pressure or whatever, at least I assume that was the reason, that every time I wanted to invite a friend over or go out and do kid stuff growing up, they would say, "What is a friend? There's no such thing as this "friend" thing. Can you explain what are these "friends" you speak of? ".
Only kids I was allowed to play with were ones they vouched for, this included a couple Somali family friends, only these particular Somali families were allowed no others which most were far away anyway so it didn't really matter, and a couple Asians and bible-thumpers on the block. Everyone else I had to hang out with through sheer stealth throughout my life up until a few years back. I became very good at keeping tons of these covert friendships, including sneaking out. My siblings say it was much worse in their childhood and I had it "good".
I guess their parenting answer to the question of peer pressure and kids making mistakes was to restrict the likelihood of our having any at all.
