Professor Requires Students To Attend Class In-Person, Doesn't Show Up Himself

Now there's the possibility that this professor might just not want to attend class because he's a senior citizen, and doesn't want to put himself at risk with everything going on in the world right now. With that being said, it would be a bit of a bummer to have your professor go out of their way to require that you attend class while they're not even there in the first place.
