Every once in a while I run out of dishwasher soap and have to do a few loads by hand until I get to the store, and I can't think of a bigger waste of time. If it was just me, or just me and the man, I'd be fine. But I've always got a load of laundry that needs folding, or some spot on the carpet that needs scrubbing, or a child who thinks she's starving to death, and I hate just being stuck at the sink when there's other things to be done.
