Why do people in anger shout at each other?

A Hindu saint who was visiting the river Ganges to take a bath found a group of family members on the banks, shouting in anger at each other. 
Smiling, he turned to his disciples and asked, 'Why do people in anger shout at each other?' 

The disciples thought for a while, and then one of them said, 'Because when we lose our calm, we shout.' 

'But, why should you shout when the other person is just next to you? You can as well tell him what you have to say in a soft manner,' asked the saint. 

The disciples gave more answers but none satisfied the saint. Finally he explained: 

'When two people are angry at each other, the distance between their hearts is larger. To cover that distance they must shout to be able to hear each other. The angrier they are, the stronger they will have to shout to hear each other to cover that great distance. 

What happens when two people fall in love? They don't shout at each other but talk softly, because their hearts are very close. The distance between them is either nonexistent or very small...' 

The saint 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. Finally they even need not whisper, they only look at each other and that's all. That is how close two people are when they love each other.' 

He looked at his disciples and said, 'So when you argue, do not let your hearts get distant. Do not say words that distance you from each other more, or else there will come a day when the distance is so great that you will not be able to find the path to return.'
