The language of silence!

I remember that one time a friend thought me that all the creatures in this world have a hidden language and the secret of being able to create relationship with them is to talk with their own languages.
Also from studying the different cultures, I learned that in some nations there is a great value for silence, and there are even some pieces in their music which means silence. The silence has a lot of vowels and meanings in different times and it can have good or bad meanings.
The father talks to his son with a deep silence after seeing him for a long time and the lover talks to her beloved with a long silence.
For the people who understand it, the silence is as deep as eternity!
