Having these people as students, as I've never would have imagine, was a lot of fun. At first they were so serious but when the lesson begins they were becoming more interrested and throw a lot of questions at you. They were also very interactive and would even respond at my jokes.
Well, it never crossed my mind that teaching would be fun. Maybe it depends on what material you are handling . Being a full time teaching? Nah, I don't think so.
