This may sound contradictory, but I had a best class ever today. Only students who regularly attend class attended. No distracting students!
I gathered them around me, and I also sat (I usually stand and walk around in class). The atmosphere was perfect: a living room kind of feeling, friendly, relaxed. I believe students also enjoyed that atmosphere in which everyone felt easy to speak up and interact with each other.
If I can have this kind of class forever, teaching is not bad at all. I don't know, I'm so ambiguous about teaching right now.
