A story about truth

One day, a rich man dropped his wallet at a market.
Than, a poor boy took it.
It was filled with hundreds of dollar.
He was wondering who the owner might be.
So, he yelled at the center of the market, "I found a wallet, anybody lost it?"
The rich man heard him, than rushed to him quickly.
He took the wallet back, counted the money inside, and said, "Hey! When I dropped it, it was filled with 700 dollars! Now it only has 500 in it! Give me the 200 back!"
Actually he was lying, and he just wanted some extra money from the boy.
The boy said, "I'm poor sir, and I didn't take anything from your wallet."
"You're lying! Let's take this problem to the court!"
So, they went to the court.

At the court, they both told the judge their stories.
After listening to them, the judge said, "Sir, you said your wallet was filled with 700 dollars. But this one is just filled with 500. So, this can't be your wallet. I'm going to give this wallet to this boy."
