Over the years I have learned of the secret powers of vacuum cleaners. They're good for sucking up dust bunnies, small scraps of paper, and coins. Anything you don't feel like bending over to pick up, a good vacuum cleaner will grab it for you. Vacuum cleaners are also great dog training tools. My dogs immediately skulk off into another room when the vacuum is pulled out. Turn that sucker on, and I can herd a pack of dogs better than an Australian Shepherd with a flock of sheep. I've also learned of the power of the vacuum cleaner to stop spousal nagging. For two days Mark has been nagging me to clean the house for Thanksgiving. So yesterday afternoon I dragged the vacuum cleaner out into the living room and leaned it against a bookcase. It gave the appearance of something being done without anything actually being accomplished, other than my being able to sit and watch television for a few more hours without being nagged.
