One particular babysitter of mine was comforting me after I became hysterical and was crying over something or other. She started cooing "Calm down, it's okay." Having never heard anyone use the phrase "calm down", I thought she was saying "come down" (as in "come down out of the tree", or off of something high off). I looked up at her and said "Come down from where? I'm not on anything, i'm right here."
