Gym class. It was like they literally didn't know how to actually teach the rules of the sports, the coaches just expected that parents and siblings had already taught their kids. Well I didn't have any siblings, and my parents never knew either.
Like, what defines a fumble, a foul, a touchdown, etc..? What the fuck does 3rd and Down mean? I'm 42 years old and still don't know most of this shit.
They didn't teach us any of that shit, they just expected all students to somehow know all those things. And they actually had the nerve to ask me, as a math nerd, if I would keep score...
Like seriously what in the actual fuck? How am I supposed to keep score on games I don't even know the rules and language to?
Edit: I wasn't exactly a lazy kid either, I loved climbing trees and riding BMX flatland, but those are simple to score. You gain points by completing the climb/trick, and you lose points when you fall and bust your ass, and there aren't even any official points when playing on your own.
