You can't build a plot out of jokes. You need tragic relief. And you need to let people know that when a lot of frightened people are running around with edged weaponry, there are deaths. Stupid deaths, usually. I'm not writing 'The A-Team' - if there's a fight going on, people will get hurt. Not letting this happen would be a betrayal.

People who used magic without knowing what they were doing usually came to a sticky end. All over the entire room, sometimes.

In my early teens, I read every bound volume of the magazine Punch. Every writer of any distinction in the English language, and I mean including America and England, at some time wrote for Punch. Jerome K. Jerome, who wrote Three Men In A Boat, I loved. I was very impressed when I read a piece by Mark Twain in Punch, and realized that despite the fact that they were on different continents, Jerome K. Jerome and Mark Twain had the same kind of laconic, laid-back, "The human race is damn stupid, but quite interesting" attitude. They were almost talking with the same voice.
