In our district, they do a "family life" unit in 5th grade, that parents can choose to opt out of. I guess it varies by locale.
Funny story. Well, funny to me
My son is now in 7th grade and, I guess, fairly clueless about all the hormone induced behavior raging around him. He has a female friend he's known since 2nd grade. Apparently one day at lunch she was talking about something and my son ("A" for this story) was acting clueless as always as were some of the other boys and she remarked something along the lines of, "I won't explain to B because he wasn't in family life, and I won't explain to A because while I know he was in family life given that he sat next to me, he must have been in some strange trance where nothing registered because he doesn't seem to have heard a word of it."
My son is really happy being clueless. Really happy.
I'm just telling him what he absolutely must know, like it or not.
