My wife collects pretty plates, so most of our crockery is not dish-washer proof, or microwave proof for that matter.
I do claim to be able to stack more on the sink-drainer, and I don't often have any sharp knives cunningly concealed under plates ready to inflict injury when you clear the washing-up away!
I get accused of pretending to be bad at cooking so that I don't get asked again. This is unfair; I really am bad at cooking.
