This is why parents choose private school, or “good schools.” It’s a proxy for controlling your kids’ social circle. Mine are too young to go anywhere without me, but when I was growing up my parents insisting on personally meeting anyone I’d hang out with alone. They discouraged going to other kids’ houses and would insist on having get together at our house where they could keep an eye on us.

Going back a generation, my dad—who grew up in a village in Bangladesh—noted that other men in the village would notice him during his several mile long walk to school. If he did anything out of sorts word would have gotten back to his father.
