This fellow is wise enough to play the fool; And to do that well craves a kind of wit: He must observe their mood on whom he jests, The quality of persons, and the time, And, like the haggard, check at every feather That comes before his eye. This is a practise As full of labour as a wise man's art For folly that he wisely shows is fit; But wise men, folly-fall'n, quite taint their wit.
William ShakespeareNever play with the feelings of others, because you may win the game but the risk is that you will surely lose the person for life time
