Today when I went to go teach class, I was greeted by all of my students sitting outside the classroom. I figured this was another case of the previous prof not vacating the room on time. I was wrong
Turns out, someone had the brilliant idea of spraying the room with pepper spray. In the course of doing this, the room was effectively unusable, so we had to find another room in which to have class. Oh well, once we got the room, everything went OK.
