Tis the season for the flake-outs....
Me: Stu A, I'm concerned about your absences.
Stu A: I took this class before and had to withdraw, so that part was review for me.
Me: ok, as long as you know what you're doing.
Stu A: I came to ask you why this proof isn't working?
Me: Because you're wrong on lines 3, 6, 7, 8 -- maybe you needed to come to class?
Stu A: Blank Look
Conversation 2 -- context, before class when I'm setting up the PowerPoints
Me: Hey, Ice Fishing Dudes (cuz they always dress like they've just left the ice house -- and wear their jackets for the whole class... kind of weird) -- was your homework to work on these rules?
IFD: blank, stupid looks... umm..
Me: So, you didn't bother to do your homework...
Also -- all three of the IFDs missed the last exam. They're allowed to take a make-up. I suspect they thought they'd get the same make-up, so one would get the questions and tell the others... but, I wrote three distinct make-up exams for them. Hmmm..... it sucks when your proffie figures out your plan, doesn't it fellas?
Other semesters I'd feel bad about having this level of irritation toward my students -- but I really don't feel bad about it at all.
