Why do we shout when we are angry?

I read this story somewhere and found it really made sense.  Here it goes:

 

A Hindu saint who was bathing in river Ganges saw a family on the bank, shouting at each other. The saint turned to his disciples with a gentle smile and asked, "Why do people shout when they are angry at each other?'.

The disciples thought for a while, and one of them said, ‘We shout because we lose our calm.’

"But, why shout when the other person is just next to you?’ asked the saint. ‘Isn’t it possible to speak to him or her softly? Why do you shout at a person when you’re angry?’

The disciples gave some  answers, but none satisfied the saint. Finally he explained, ‘When two people are angry at each other, their hearts are far apart and distant from each other, and in order to cover that distance, they must shout to be able to hear each other. The angrier they are, the louder they will have to shout to hear each other and cover that great distance.’

Then saint then asked, ‘What happens when two people are in love? They don’t shout at each other but talk gently and softly because their hearts are very close to one another. The distance between them is either imaginary, non-existent or very small.

He then continued, ‘When they love each other even more, what happens? They do not speak, only whisper and they get even closer to each other in their love. They need to only look at each other to understand what the other person has to say. That is how close two people are when they love each other.’

MORAL : When you argue do not let your hearts get distant, do not say words to add more fuel to the flame that distances each other further apart, else there may come a day when the distance is so great that you will not find the path to return.
