Once upon a time, there was a rich man. He spent all his money carelessly and became a poor man. He had no money, no home, nothing. He only had his old clothes. One day in early spring he saw a Swallow. He thought that summer had come, and that he didn’t need his coat. So, he sold it.
However, a change took place in the weather. There came a sharp frost. It killed the unfortunate Swallow. When the poor man saw the dead swallow he said, “Poor bird! You died of cold and I am going to die of cold myself because of you.”
One swallow does not make summer.
