Princess: "MOMMY! MOMMY! Bad said the 'S' word!"
Me: "Really?....what's the 'S' word?"
Princess (leaning in to whisper in my ear): "Stupid!"
Me: "Bad - did you say 'stupid'?"
Me: "Did you call your sister 'stupid'?"
Me: "Then what did you call stupid?"
Bad: "Ken's shirt."
Me: "Okay....Princess, you're right - stupid isn't a nice word and we should try not to use it. However, Ken's shirt IS stupid, so let's just let it slide this time, alright?"
