Do you hold yourself to a different standard than other people?

A number of my friends and colleagues are teaching classes right now for which they determine the classroom policies. I have repeatedly seen them create rules that they themselves are lousy at following. For instance, one of teacher told her students not to bother coming to class if they were going to be late—and then had to ask me for a ride at the last minute because she hadn’t left herself enough time to walk to class.

Another teacher just said that she doesn’t want to bother giving a review session the night before the exam because she doesn’t want to “help them cram.” Perhaps she’s the only person in the world who has never studied the night before an exam, but everyone else I know everywhere else in the world budgets their time around deadlines and does the bulk of the work as the deadline approaches.

I guess this was more of a rant than a real question, but I was hoping those of you with more patience than me could give me some perspective….why do people do this? Or do you agree with their decisions…am I way off the mark here to think they’re holding people to unreasonable standards?
