I stand in the middle of a valley. I call myself, loudly very loudly. I get a echo back and one echo generates many echo. I am surrounded with echoes.  I call my name again and echoes come rushing. I go silent, hoping that valleys will call and I will give them the echoes back. It does not happen. Me, mountains and nature communicate with each other day after day but we don't use words, we don't use voice. The communications only through appreciation.
