I know what you meen about the good and bad lessons, I have the same problem with one of my classes (is it wierd that I enjoy waking my students with a kick to the chair?) but then I have another class that I look forward to teaching everyday. I'd take the Avatar jibe as a compliment, what I'd give to be over 6 foot and blue. Hope your water gets sorted out, get some photos of your students and classrooms, there's just not enough going around.
