I know this guy who's like a modern day Johnny Appleseed. But instead of tossing seeds from a burlap sack, he changes every burned out light bulb he comes across. He walks the earth with an irrepressible mission to enlighten our lives with a constant flow of fluorescent and tungsten brightness. Am I one to judge? Am I, like others,to mock his quixotic calling, to belittle his burning heart?
