For me, being horny at random times, and navigating the social hierarchy were annoying, as was what I perceived as social injustice.
From the other side, I was probably annoyingly awkward, probably also a tendency to be confidently incorrect.
I was raised in a stupid conservative extremest religious environment that warps my perspective. I’m curious what makes teens uniquely different. I am also partially disabled and in near total social isolation for a decade now, so the overarching question is more a distant abstract idea to me.
