Why is washing up one of those things people hate to do, when they still need clean plates to eat from? When sharing a flat or a house you can bet if there is a disagreement it is going to be over the filthy plates in the sink. Even among family siblings quarrel over the washing up. Now that there is the dishwasher, I hear something else. “Who did not scrape the food from plates before loading the dishwasher?” Sure, the plates are still filthy.
