I miss my on-campus classes.

Nothing causes a better high than seeing the light bulb moment--that moment when a student understands something for the first time, and their face lights up with sudden understanding (and often chagrin, when they realize how easy the concept I was trying to teach actually was, and how much harder they were trying to make it on themselves). 

It's something that's entirely missing from teaching online.  I get it a little bit with the kids, but there's still a major communication barrier, and it's really muffled. 

There is a great joy in staying home with my kids, but that joy has not come without sacrificing the classroom, which was the part of teaching I loved the most.
