Crying is not limited to humans. Even animals cry.
Crying is not limited to the flow of water coming through our eyes. There are scenarios, situations in our life where we have got a limited choice. The situations which need us to take action on short notice.

* Rare chances of survival for the wife of a tea seller. Even after selling his tea stall, he could not pay the operating costs.
There are some situations where we can show rationality to outside.
