I understand that Logic, but there have been times when the professor never showed up and we ended up wasting our time. paid or not. :P
Not true. You can never predict if your professor will show up for the day or not—there is always a chance of something happening—and assuming that an email of cancelation was never sent out, “wasting” your time is just you being a good student and showing up.
There was one case that this happened, and the professor did show up 20 minutes late due to a car crash that clogged up the freeway heavily.
Either way, it doesn’t mean you can’t work on other things while you wait…or play a few games. I:
