There was once a starving wolf in a sorry state. He had been obliged to flee from a pack of dogs and for many days he had found nothing to eat.
He spied a little white sheep and thought 'At last! Here is a meal for me!'
'Little white sheep,' he said to her, 'could you please get me a drop of water from the river? as you can see, I am very unwell. If you can bring me something to drink, I will be able to find something to eat.' 'But if I bring you something to drink,' said the little sheep, 'then already have found yourself something to eat!' and skipped off in the opposite direction.
