If ever I could count on the unquestioning service of a perfectly obedient robot that could be available at all times to relieve me of only one nightmarishly awful chore, I should very much like to have one that would shovel snow for me. When it comes to difficulty all other chores very much seem to pale by comparison. This is made especially true by the fact that it’s always outside in miserable weather. Bad weather in general has always bothered me. Snow and ice get me crazy. I’ve never been known for an abundance of physical strength and shoveling is one of the things that require quite an exceptional degree of endurance. By definition a robot doesn’t have to deal with frustration and exhaustion. All it needs is either a plug, battery or some other power source. Unlike me it will never complain about hypothermia or boredom. I should only need it for part of the year anyway, although winter, when it gets here, seems so unbearably long.
