Birbal’s Wise Decision – example of creative problem solving

A farmer and his neighbour once went to Emperor Akbar’s court with a complaint.
“Your Majesty, I bought a well from him,” said the farmer pointing to his neighbour, “and now he wants me to pay for the water.”
“That’s right, your Majesty,” said the neighbour. “I sold him the well but not the water!”
The Emperor asked Birbal to settle the dispute.
