professor who is 16 minutes late and finds their entire class gone: where is my class
some dude who sits in the back row of class about to invent the if the teacher isn’t here in 15 minutes we can leave rule: oh, you haven’t heard?
I’m an instructor and I know for a fact when I’m 1-2 minutes late my students are saying this about me
and when I was a student, I was one of the people saying it
to this day I still do not know where that rule came from
