A long time ago, a farmer was working every morning. His name was Songchai. Every day Songchai would go to work on his land. One day, Songchai had to cross the woods. As soon as he started out, Songchai saw a king cobra. He very much pitied that king cobra. "It's injured," Songchai said. "Oh, I will help it." When Songchai helped the king cobra, the cobra didn't move. But after he helped it, the cobra turned back to attack his leg. The motto is, you have to know about the disposition of someone before you go to work with them.
