Just another datapoint, I've never seen anyone do that (I don't live in urban CA). I think you've just experienced how insular communities can descend into (I'm not trying to offensive in saying this) self-parody at blinding speeds, if they're cut off from outside mixing for too long.

I'm quite sure they were saying they've never seen this happen:

"but kids will bring home a note with the contact details of their playmate, and their parents will schedule it. The whole calendar scheduling, driving, chaperoning etc are things that definitely happens."
