looking back, how was elementary or primary school traumatic and toxic for your childhood?

When I was in third grade, I had to pee really bad during class one day and my teacher outright refused to let me go. I wound up pissing my pants.

That taught me very early on to not always listen to authority. Had a teacher try to pull the same thing when I was in ninth grade, but I ignored her and went to the bathroom anyway. Got ISS over it and it was worth it.
