Last year, when I was in first year, I took a 300-level theatre course. We had two profs, and one of them (the one in this story) is about 60 and incredible...she definitely marches to the beat of her own drum, but she's an absolute sweetheart (and can out-work-out everyone by a mile!). Anyway, there was one class where we (the professor and the students) were sitting in a circle discussing an assignment. All of a sudden, the door opened and a student rushed in, looked around the room, realized he was in the wrong classroom, apologized and rushed out. Everyone giggled awkwardly and resumed discussing the assignment. Our prof, however, leaned over to me and whispered, just loudly enough for me to hear:
"Good thing we weren't having an orgy or that would have been REALLY embarrassing".
Needless to say, first-year-student-me was corrupted from that moment on.
