Substitute teachers.
Haven’t had a substitute teacher in college yet, but I’m pretty damn sure they wouldn’t be as awesome as high school subs. Where else do you get to meet the following: a retired engineer/mathematician with expensive sports cars, a former writer for Rolling Stone, an unemployed college graduate with a degree in “art,” a twenty-something hipster, a creep with a huge ass hand, a man who walks with a perpetual limp, a former postman, and a guy who can quote Napoleon Dynamite like it’s part of his job. That’s what I miss.

Haha, who was the retired Rolling Stone writer? and btw dude if there’s no professeur the class is canceled lol. As far as I know, substitute teachers don’t exist in college lol.
Wish we could do likewise in high school, just cancel class. It’s too hard to prepare for a sub. And then you get those subs who don’t know what they are doing.
Heh, exactly. One of my subs last year told the department coordinator that the kids didn’t want to do the worksheets, so he didn’t hand them out. Aw-oh!
