Emperor Akbar liked to spend time watching the river Yamuna from the palace terrace at nights before retiring to bed. Some times Birbal would also join him on the terrace and they would have conversations about a variety of topics. 
One summer night, while they sat in silence, listening to the river flow, Akbar asked, “Why does Yamuna cry, Birbal?”
Without a moment’s hesitation Birbal said, “It is in the nature of young women to cry when they are married off.”
“Explain”, said the Emperor curiously.
“Young river Yamuna has been staying with her father the Himalayas. Now she is on her way to meet her husband the mighty ocean. So along the way from her father’s home where she grew up to her husband home where she will spend the rest of her life, she is crying!”
Akbar was pleased with Birbal prompt but poetic answer.
