18．Gestures are the"silent language"of every culture．We point fingers or move another part of the body to show what we want to say．It is important to know the body language of every country，or we may be misunderstood．
In the United States，people greet each other with a handshake in a formal introduction．The handshake must be firm．If the handshake is weak，it is a sign of weakness or unfriendliness．Friends may place a hand on the other's arm or shoulder．Some people，usually women，greet with a hug．
Space is important to Americans．When two people talk to each other，they usually stand two and a half feet （69centimeters） away and at an angle（角度），so they are not facing each other directly．Americans get uncomfortable when a person stands too close．They will move back to have their space．If Americans touch another person by accident，they say，"Pardon me"or"Excuse me"．
Americans like to look at the other person in the eyes when they are talking．If you don't do so，it means you are bored，hiding something，or are not interested．But when you stare at someone，it is not polite．
Learning a culture's body language is sometimes very difficult．If you don't know what to do，the safest thing to do is to smile．
