" the rest are trying to hide the fact that they are sleeping."
I always shock my students on the first day of class when I tell them I don't care if they sleep in my class. I say I'd rather have them in class sleeping than at home sleeping, because in class they might wake up and learn something. Of course, far too many of them take me up on the offer.
