Just a few days till tax time! Worried? Not me. Not to brag, but I had my tax return done before the Christmas holiday was over. (Yeah, I'm one of those people.) So you'll understand that I felt a mild panic setting in during a recent Web session; I was cruising Y2K sites to learn more about the millennium bug, and one peddler after another exhorted me to "buy today, while supplies last." And I did. Sure, my credit card is maxed out now, but look on the bright side: I am the proud owner of all the astronaut meals and water purification paraphernalia I'll ever need. Besides, I don't intend to settle my bill until after January 1, when Visa's computers will assume it's the year 1900 and all my debt will miraculously disappear. Oh, happy day!
