     An old man died and left his son a lot of money. But the son was a foolish young man, and he quickly

spent all the money, so that soon he had nothing left. Of course, when that happened, all his friends left him.

When he was quite poor and alone, he went to see Nasreddin, who was a kind, clever old man and often

helped people when they had troubles.

     My money has finished and my friends have gone, said the young man. What will happen to me now?

     Don't worry, young man, answered Nasreddin. Everything will soon be all right again. Wait, and you will

soon feel much happier.

     The young man was very glad. Am I going to get rich again then? He asked Nasreddin. No, I didn't mean

that, said the old man. I meant that you would soon get used to being poor and to having no friends.
