I've been in Uni for a few years now and I have to say the "weird kids" to me aren't the ones with dyed hair, the ones that play their Switch on campus, or even the guys who don't shower.
No, the weirdest kids are the ones who show up to class everyday just to talk their heads off in the back of the room. Can you imagine that? Imagine spending 10K to dick around instead of actually pay attention.
we call those people "backbenchers" over here lmao, and they're pretty common over here actually
unless the teacher is a strict one, expect them on the back/middle to [albeit a bit quietly] yap about stuff even while class is going on
but yeah, i also wished they'd wait until the class was over because goddamn it makes it hard to concentrate sometimes 😵💫😵💫
In my case, they straight up are in competition with the teacher for who gets to talk. I don't know if they're unintelligent or truly lack self awareness but they rarely ever stop on their own. It doesn't help that everyone in class (including me) doesn't want to say anything. I think we all realize that trying to shut them up would just lead to an argument and nothing would get done.
I'm just sending out emails asking someone in charge to give a shit since half the class is just not showing up anymore.
