So I’m (18F) attending a course in my high school about writing. It’s in the afternoons after class and I took it because I was genuinely interested. There were some friends there, but there was also this girl Marie(18F). Marie and I aren’t close at all but she is super friendly and nice with everyone (she always has a smile on her face, to put it that way). We were working with a special kind of pen (don’t remember the name) but it was special because the point need to be held at an angle, 45° to be exact. When we were trying it she explicitly said “what is an 45° angle?” to which I jokingly replied “that one friend that failed elementary school” (yk like those memes like “that one friend that’s too woke”)because I thought it was a harmless joke and we all were in the mood for jokes but she saw me with a horrible face, literal killer eyes, her expression was a mix of judge, anger and like disgust (?). That was today and I feel like I really fucked it up and I feel terrible because like I said i’m not close to her at all, so AITA?
