FORGET THE PAST AND MOVE ON

A wise man once sat in the audience and cracked a joke - all of them laughed like crazy. After a moment he cracked the same joke again & a little less people laughed this time... He cracked the same one again & no one laughed !!! Then he smiled and said ''when you can't laugh on the same joke again & again

then why do you keep crying over the same thing over & over again''   FORGET the past and MOVE ON ...
