Thoaty Voice

I talked continuously for three hours today. Two tutorials and a lecture. I've got nice, husky, tones as a result at the moment. By the end of it I'm afraid that both me and the students (it was all the same group) were finding the art of drawing Collaboration Diagrams perhaps a bit less inspiring than it might be. Sorry folks, I'll be back to my wise cracking, enthusiastic, form on Tuesday (as if you can wait).
