I've been washing a lot of dishes by hand lately, due to a broken dishwasher. I kind of like it. It gives me time to think while I wash.
Often my mind wanders to a simpler time when I was a child washing dishes for my grandmother. She always told me to get the water temperature as hot as I could stand it. Of course, she could always stand it hotter than I could because of her experience with it, and I was just a newbie back then. There is one important lesson I've learned while the dishwasher has been out -- washing dishes is like riding a bike.... you never forget how.
