One day, a farmer works in his fields. The wind blows hard. He feels very cold, so he goes home.

On his way home, he saw a frozen snake. He picked it up and put it in his chest. He tried to warm it. Some time late, the snake was warm and active. It bit the farmer in the chest.
The snake was poisonous. The farmer was dead. Before he died, the farmer said, “I’m so silly. I look at an enemy as a friend.”
