@inthehands I remember when the period discussion came to our Middle School classroom (we called it Junior High back in those days).
The girls were spirited away and instructed separately; we boys were not to badger them or discuss it further when they returned from their unprecedented sequestration.
I, of course, had informants who filled me in on the substance of the lesson. And that was that!
It was all very interesting, memorable, and good to know.
