I am neither an expert of studies on conversation nor a counselor of how to speak with individuals or address an audience. I have pity on myself why I try to put a big morsel in my small mouth by choosing a profound and scientific topic for my today’s post! I question to myself, “How dare you (Mr. Author) put on an Armour without having a sword in hand?” But, I am prepared for ‘Come what may!’ I recall Narmad, the brave (a Gujarati man of letters) with his call ‘Go forward and victory is there waiting for you.’ *
