Man not to be like, "Back in my day" but when I was in school, I literally wasn't allowed to hang out with my friends from my neighborhood during breaks because we weren't in the same grade. That I feel was unnecessarily controlling; not singing the same song more than 3 times in the teacher's earshot during breaks? Not so much. (also like, if he's doing it far away and kids hate it enough to narc on him, I feel this policy is still doing him a favor in the long-run)
