When we were growing up, our mother was the primary handyman...uh, handyperson of the house. Our father could assemble a computer from parts alone in an instant, but changing a lightbulb would cause him to throw up his hands in horror...yeah, it didn't make much sense to us either. The one tool he held with complete confidence though, was a screwdriver.
