HOW THE CLOUDS ORIGINATED?

     "Listen! They admire our nice sky, what else."
     "Hmm!" said Sky-man. "What can I do? They are so silly that are going to starve."
     "Yes, I thought about this," said wallah Jaen and he had a suggestion: 
     "We have to make lovely curtains and hung these. What do you think?"
     "The curtains?! Hmm-yes, curtains… It's not bad idea," said the Sky-man. Next day they made curtains. These didn't let to admire the beauty of sky. And from this time people started to work and don't admire the sky.
