I had an argument with a lecturer at my uni. He was such an asshole, never had someone in a teaching position be such a downright prick. Called him out as being complete bullshit, and yikes I never do that.
I had a separate class after that encounter, which I left early because I was fuming. I get to the elevator as I'm on level 6 and go down to ground floor. The elevator dings at level 5 and this prick lecturer gets in the elevator. He has the nerve to say "you don't look happy" and all I said was "no shit" and waited to fking reach the ground so I could walk home. Man that was terrible.
