What is valuable?

What is the value of something? It depends. There was a happy man of the country who knew the value of a good milk producing cow, but nothing of diamonds and sapphires.

One day the king was passing by his barn when a tree fell upon the king's carriage and the happy farmer saved the king with a rope and a cow.

As a reward for the effort the king took the farmer to his treasury and told him to take whatever he wanted. He immediately spied a few wooden stools, a pile of sacks, brooms and wooden boxes. The king said, but you don't understand, I'm offering you great riches.

The man said, what are riches? I think I'm rich already, but I can always use these supplies, thank you very much. He picked up his valuables and he walked out of the treasury.

What are riches? Hmmm.
