"Do not argue with a fool, for people will not be able to tell between the two of you."
~African Proverb 

Most arguments are about proving the rightness of a point of view. Suppose you come across someone who isn't willing to listen to your side of an issue? Be kind. Let him or her win the argument and move on. Follow Wayne Dyer's advice: "When given a choice between being right or being kind, choose kind."
