Annoyed by something stupid

A few years ago, I was obsessed with anime, and my classmates used to make fun of me for it. Fast forward to today, and suddenly those same people have spent days talking about anime in front of me like they’re absolute experts.    They literally asked me, "Hey, do you know Jujutsu Kaisen? You probably haven't heard of it."                                                                                                               I know I shouldn’t let something so stupid upset me, but, honestly, it’s annoying. I hate the popular kids in my class.
