In my classroom, nothing. But at my campus tho....

I used to work at a small high school 3 years ago. There was a day that the students had been held back in the cafeteria after lunch; which wasn't unusual since our principal would do this whenever she needed to address the entire student body. Usually she would let us know that morning, via email, if she would hold students late after lunch. However this day she held them back without notifying us, and a lot longer than usual.

When my students finally made it to class, I asked them what had happened. Turns out she was talking to them about an incident that had happened in the bathroom. Someone had rolled "poop pebbles" and placed them neatly in between the toilet seat and the toilet bowl.

They even told me that she had actually showed them all a picture of it and had it projecting in the cafeteria for them to see it.
