My co-teacher is out-of-town and I had planned to teach the class alone today. But the people in class last Friday (I was out) requested that we skip today because so many people were going to be gone this week and they didn't want to miss two classes in a row.
I guess that means that we have made the class frightening enough that the class feels they can't afford to miss much. Either that or they are expressing their horror of the idea of me teaching the class by myself. Either is possible.
