We are nothing if not polite...

Today on the way home from the store, Lincoln was making lots of loud babbling noises and Chloe couldn't hear the music. Finally, she had had enough and turned to him and said, "Shut up, Lincoln!" I immediately reacted, telling her not to say that, it was not a nice thing to say. She then calmly turned to him and said, "Lincoln, will you please shut up."
