Class Cancelled

I showed up for class at 11:00 this morning only to learn that the professor had announced by email at 9:45 that class was cancelled. This is typical. Sometimes we get no notice at all: we'll show up to class and there will be a sign on the door. I'd say this has happened to me five or six times in my year-and-a-half of law school. That isn't a whole lot, but it's annoying as heck when it happens.
