" It is unimpressive to speaking rudely to others. Often, all we need to do to ensure that we do not launch into a rude remark is to pause . . . breathe . . . and smile to ourselves before speaking.
And when people are rude to you, just remember that they are revealing who they are, not who you are. Don’t take it personally. Sometimes being silent is your best response. "
