I subbed today for a high school social studies teacher.
My 4th period class was out in one of the portable classrooms behind the school. I'm glad I made sure to get there early, because the heat hadn't been on all day and it was freezing in there. His lesson plans also strongly implied that the rest of my classes for the day were out there. Since the building did not have bells, and its clock wasn't synced to the building clocks it took a couple extra minutes for me to realize "oh, hey... no kids are showing up." I was a couple minutes late for my next class. Oops.
Apparently one of the teachers at this school told the kids that I am mixed-martial arts instructor, and that there are a handful of states I'm not allowed to teach in because my hands are considered "deadly weapons." I picked up on what they were talking about just in time to act very humble and say, "I can't really talk about this."
Sadly, the teacher was gone today so I couldn't ask him about it.
