Uhh, elementary school is still 1st-6th right? So like what, age 5/6-11/12? That top end is easily around puberty for plenty of people. Hell, I knew people in 6th grade that had sex. I also know that my BIL knew he was gay in elementary school.
I thought that elementary school usually ended at around 9 and then off to middle school. I mean maybe some kids at 9 might have a reckoning but I would think it would be rather rare.
