At my house, I am the one who loads and unloads the dishwasher. Other people, (whether by design or lack of brain cells), just do it wrong. I can pack in twice as many dishes, correctly loaded, and have them come out clean as you'd want, compared with anybody else who loads them haphazardly, and gets spotty results.
Come to think of it, I'm also the one who loads the car for family outings, the moving van whenever we have moved to a new house, and suitcases in the trunk when we're headed for the airport. Others around me, for as much as they mean to me, just do not get it. I can't tell you how many times I'll finish packing or loading something, making "ten pounds fit into a five pound sack", and I hear, "How did you DO that?" I can't explain it, I just know what goes where. Too many years of living out of a suitcase, I think.
