A wise man once sat in the audience & cracked a joke. All laughed like crazy. After a moment he cracked the same joke again and a little less people laughed this time. He cracked the same joke again & again, When there was no laughter in the crowd, he smiled and said "When u can't laugh at the same joke again & again, then why do u keep crying over the same thing over and over again?'
Forget the past & move on..
