Just now I was in my kitchen washing the dishes that were too large to fit in the dishwasher that I had just loaded. Isaac finished his lunch and brought his plate over to where I was standing and asked, "Should I put my plate in the sink or in the dishwasher?"
"Put them in the dishwasher, please." I answered.
Isaac loaded his plate and asked, "Why do we have a sink and a dishwasher?"
Before I even had a chance to open my mouth he answered his own question, "Oh. In case your mother dies. That must be why."
