This kinda cracks me up. I hear this from W all the time...that unless I do it "right" (e.g. HER way), I might as well not do it at all...BUT...(and that's a big 'but') she suspected that I did it "wrong" just to get out of doing it. Nope. I did it "wrong" because that was just MY way of doing it.
However, I am the chief/best/master dishwasher loader in the house. No one does it to my satisfaction. The difference is, I don't tell them they did it wrong (whether it's the kids or my wife), I just re-do it. I have told the kids the basic principles I try to follow: dirty side toward center of dishwasher, don't put all silverware of one type in one section of a basket (they NEST!).
