• Several months ago, out of the blue, a company named "Cingular" started sending me bills. I had never heard of Cingular, and I honestly did not know what these bills were for, so I put them in the pile where I keep documents that I intend to scrutinize more carefully later on, after my death. Then I started seeing TV commercials for Cingular, but of course they did not make it clear what Cingular is, because the First Rule of Modern Advertising is: "Never reveal what you are advertising."
