What is going on?

This is a conversation that I heard during my accounting class yesterday...

"do you have any idea what is going on?"
"no, and where did he get those numbers from?" (disregarding the teacher who just explained it 30 seconds earlier and the printout of the slides they had in front of them)
"this is going to be a really hard class, and I thought this was just an intro class"
"well have you done the homework?"
"no, how about you?"
"no, and I don't think I will be doing any of it this semester"
"why do they expect us to take these kind of classes?"
"I don't know, and what happened to college being about parties and stuff like that, no one ever said anything about having to do so much work"
"if I could drop this course I would, but since I can't I think I will just stop coming to this class"
"me too"

...and it's such a mystery why you are lost
