* You go into your class, completely unprepared....and realize that today is the day you are being observed. By the person who will probably have the biggest influence over whether or not you get tenure.
* Even your most favorite students are annoying the hell out of you.
* Every time a student comes to your door, you want to yell, "Go away! Just go away and give me 5 minutes of peace!"
* You know all of your colleagues are in, but everyone's door is shut. Tight.
* The lecture you gave in class today bored even you.
