Actually,we didn't need to speak and talk for communicating with others.We can also use signal or gestures to communicate.For example,we are hungry,and we make a sign which put our near to our mouth and tells that we wanted to eat something,also put our palm at our stomach and spin it slowly.In military,when they in combat or on a operation,they do their job silently so the enemy cant detected them.How their communicate?Their off the radio for a period,and use gesture to lead their team member.Show what they should do and where they should go.Not everyone can really understand this non-verbal communication,we must do it effectively to make others understand.This kind of method offently used by those people who cant speak and listening.So be thankfull that we can speak and hear...
