At the end of the Shabbos seudah, my sister wanted to take my 5-year old niece home because it was getting late, so she told her to put on her coat so they can go home. My niece didn’t want to go home yet, so she said, “No”.
My sister rebuked her for being rude. She said, “But I said it politely.”. So my sister said, “It doesn’t matter if you said it politely. It’s rude to say no to your mother. Now put on your coat.”
“No, thanks”, my niece sweetly answered. And couldn’t understand why we cracked up.
