It seems I have a knack for this. I just thought of another one. I was at a football game watching my old high school play in a big game ten or so years after I graduated. I don't want to out myself so I'll not name the teams, but it was at the opposing stadium and it was homecoming for that school. We ended up sitting with some other people who had been in my class in the visitors section. These were all people I had been friends with in high school, had multiple classes with, and in most cases still had occasional contact with. The homecoming festivities are in full swing at halftime and I'm ragging on the whole tradition of the homecoming king and queen. I come out with "I mean seriously, who even remembers who our homecoming queen was?" Turns out she was one of the people sitting with us and probably one of the nicest, most fun people I know. She turns around and says "I was the homecoming queen!" She was laughing, thank goodness and we all had a big laugh about it, but I felt about two inches tall.
I still see her every now and then as she's a teacher in the district and very well regarded by everyone. She still teases me about it on occasion.
