I literally hate my college

why does no one talk about how messed up the way students are treated in college is, or maybe it's just my college that’s like this. like, i was wearing a simple bracelet with spikes and the supervisor literally forced me to take it off, saying i could “harm others” with it. like wtf?? literally every 2nd student have a knife with them or something even more dangerous, and she thinks my bracelet is the problem?? what even gives her the right to tell me to take it off. and then the next absurd thing was that we’re apparently allowed to bring snacks and drinks to school, but when the supervisor saw that i have energy drink, she snatched it from my hand. LIKE WTF. what does it have to do with it being 18+ if my parent bought it for me and the shop clerk sold it to me? what’s the issue?? am i damaging my own health or not—what's it to her??ughh, maybe she just has something against me or smth cause people in my country act like that alternative people are monsters. im not saying im alt because of my bracelet or anything, actually they know that im metalhead and they call me satan and whatever yk
