19.On a Friday night,a poor young artist was playing with his violin at a street corner with a large piece of paper on the ground.Before long,he was surrounding with people,who were all attracted by the word on that paper.It said, "Last night,a gentleman put an important thing into my hat with mistake.Please come to claim them soon." Seeing this,people wondered why it could be.Some time later,a man came and take back his lottery which won a prize of $500,000.When asked why he didn't keep it for himself,artist said, "While I don't have much money,I live happy.However,if I lose honest,I won't be happy forever."
