Aesop's Fables

  Play mean tricks on people and they may play them back on you. (p. 29)

    I thought that playing a trick on people doesn't make opponent good feeling. And people who was played a trick must feel miserable. So if we want to play a trick on someone, we should use trick which make opponent happy or please.
