If you applied your DC’s school rules to when you went to school, would you be in more trouble or less trouble than you were? What decade was it? I would definitely be in more trouble, despite behaving well. Your behaviour has to be identical, so no adapting to current rules. E.g. on in between weather days, we would chat outside with our jumpers tied around our waists, which was considered totally normal. (I still consider it normal, but maybe I’m a dinosaur).
This was in the 90s, that blissful (rose-tinted perhaps) era in between corporal punishment and zero tolerance.
