Lesson in Life :')

A wise man sat in the audience and cracked a joke. Everybody laughs like crazy. After a moment, he cracked the same joke again. This time less people laughed. He cracked the same joke again and again. When there is no laughter in the crowd,
He smiled and said :
"You can't laugh at the same joke again and again, but why do you keep crying over the same thing over and over again?"

We can learn something in life based on this story :)
