Walking one evening along a deserted road, Mullah Nasruddin saw a troop of horsemen rapidly approaching.
His imagination started to work; he saw himself captured or robbed or killed and frightened by this thought he bolted, climbed a wall into a graveyard, and lay down in an open grave to hide.
Puzzled at his bizarre behaviour, the horsemen - honest travelers - followed him.
They found him stretched out, tense, and shaking.
"What are you doing in that grave? We saw you run away. Can we help you? Why are you here in this place?"
"Just because you can ask a question does not mean that there is a straightforward answer to it," said Nasruddin, who now realized what had happened.
It all depends upon your viewpoint.
If you must know, however, I am here because of you - and you are here because of me!
