Inderjeet sat leaning against a rock, his turban was over his eyes and the warmth of the sun on his bare feet. His feet told him where he was. They knew the feel of the sand and the stones, and the different kinds of grass. To his right a bird twittered. It seemed to Inderjeet that he knew what it was saying. He used to dream of flying with the birds but he never told this to anyone except his brother Deepak and his grandfather. They never laughed at him for his fancies because he was blind.
