Pet Peeve

At the end of nearly every class, as soon as the professor intimates that he or she is wrapping things up there's a cacophony of slamming books and shuffling papers. That sort of rush for the door was standard operating procedure in high school. It was kind of annoying in undergraduate school. In law school it seems completely out of place. Where are these people in such a hurry to go? Everyone in the class has the same schedule. The worst of it is, the professors usually finish the class with a word about our reading assignment for the next class. That is often completely swallowed up by the din.
