The foolish wives

Long ago there was a man with two wives. One of them was young. She had long black hair. The other was old. Her hair was white. The man was not young and he was not old. Some of his hair was black and some of it was white.
They were all very happy but the young wife thought, ‘My husband is older than I am. His hair is gray but my hair is black,’ and the older wife thought, ‘my husband is younger than I am. His hair is gray but my hair is white.’
They did not say anything but they decided to do something. Every day, after dinner, the man had a little sleep. First his old wife came to him and pulled out some black hairs.
‘That is much better,’ she said. ‘I am making your hair white and beautiful.’ Then she went away. Then the young wife came. She pulled out some white hairs.
‘That is much better,’ she said. ‘I am making your hair black and beautiful.’
They did this for many weeks. One day the husband woke up. ‘My head is cold,’ he said. He touched his head. ‘I have no hair!’ he said. There was not one hair on his head!
