child trying to get out of unloading the dishwasher

A: “Did you run the dish washer last night?”
Me: “Yes I did.”

A: “Well, there’s one knife that’s really dirty and that tells me that everything in the dishwasher is really dirty.”
Me: “Put that knife in the sink. I know I ran the dishwasher. Not everything will be dirty.”
A looking sly: “Well, it tells me that everything is probably dirty.”
