In a college classroom, though, you make a decision about whether to ride hard on that stuff (in which case, hello, constant vigilance!) or whether just to keep a running mental demerit sheet and repay the favor in those instances when a grade hangs in the balance and a decision must be made (mercy or justice? hello, justice!).

LOL. I'm a TA this term (I'm opting for the latter, for the record), and this has to be the most hilarious chacterization of the dynamic I've ever read.
