There was once a frog that lived in a well. One day, a soft-shelled turtle came by and told him about the sea. “The sea?” Said the frog. “Hah! It’s nothing but paradise in here. I assure you, there is no place in the world that is better than inside this well. Why don’t you come down here and share my joy?”
The turtle tried, and failed as the mouth of the well was too small. “Why don’t you go see the sea instead?”
Moral: Some ignorant people know nothing and refuse to know beyond their own world.
