People have been coming to the wise man, every time complaining about the same problems. One day he told them a joke and everyone roared in laughter.
After a couple of minutes he told them the same joke and only a few of them smiled.
When he told the same joke for the third time no one laughed anymore.
The wise man smiled and said:
– You can't laugh at the same joke over and over. So why are you always crying about the same problem?
