A group of people were travelling in a boat. One of them took a drill and began to drill a hole beneath himself.
His companions said to him: “Why are you doing this?” Replied the man: “What concern is it of yours? Am I not drilling under my own place?”
Said them to him: “But you will flood the boat for us all!”
Moral of the story: Our life is not just for our own. Every action and decision made affect one another.
