I‘m about to crash out because of bad smelling majors

Its only my one CS class that smells bad whenever I go, I feel the need in my brain to address the elephant in the room and tell everyone I‘m kinda pissed off and I‘ll start bringing room freshener from next time, its just a thought that came in my head while I was sitting in that smelly room I dont wanna be an ashole but also don‘t wanna shut up and stay untrue to myself because I dont wanna come off as rude
