Leave snake alone

One cold day in winter, a farm- worker was mending some fences when he found a snake. It was covered in snow, and stiff with cold. In a few more moments it would certainly die. "It's one of God's creatures," thought the farm-worker. "It would be a shame if it dies when I can help it." So he put it inside his shirt to get warm. After a little while the snake recovered, but instead of being grateful it bit the farm-worker, and he dropped dead. "What an idiot," said the snake to itself as it crawled away. "Did he really expect me to stop behaving like a snake ?"
