I always am in a state of semi-annoyance in February, because there are so many things demanding my attention at once: faculty meetings, committee proceedings(graduate admissions committee has to read all the applicant files and pass judgment on them), classes, exams, correcting exams, trying to fill out grant applications. Students have a similar set of concerns, especially those at our school, since almost everybody works in addition to going to school. February just is not a very good time, and the weather is awful, compounding everyone's feelings of gloom.
Well, I think I have the just the thing for your bad mood. Go read this post from the father of a Baghdad college student and get a sense of what students and faculty face there, during their round of midterm exams--yes, they are taking them, too, right now.
I'm stunned and sobered. You really don't think very much about people giving and taking exams under constant threat not of FAILURE, or a BAD GRADE, or TOO MANY TESTS TO GRADE, but DEATH!!
