Dave, incidentally, apologized for "putting me on the spot." Thinking about that, being surprised by that, I realized how much I like being put on the spot. That is, I love trying to answer the fundamental questions, the questions that people are all too often too polite to ask, the questions that cast doubt on the validity of the whole organization of my life. Both because I know people will be interested in the answers to those questions, and because I am really a reactionary thinker, rather than a creative one. (And there's always the possibility with such questions, however remote, that I might actually learn something by trying to answer them.) So ask, please!
