I'm definitely the architect and also pretty good at dishwasher tetris. I can fit more in the dishwasher than anyone else and I keep all of the dishes with their dirty surfaces facing the center of the dishwasher from which the water is sprayed. It drives me bonkers when people load plates facing in one direction all of the way across the dishwasher because that means half of the plates are having their bottoms sprayed, not the dirty side.

Loading the dishwasher is a science that I am trying to properly train my kids to follow. ;)
