　　The distance at which two people stand when having a conversation varies from culture to culture. Studies have shown that most Americans feel uncomfortable if they stand too close to others when talking. They feel most comfortable at a distance of about 50 centimeters.

　　Another social custom is that Americans, like many other people, often express themselves with their hands when talking. They may show a conversation or they may pat a childs head to show their affection for the child.

　　Many Americans find silence uncomfortable. They will talk continually to fill any pause in a conversation even if it lasts only for a moment. If you are silent for long periods of time, they will do their best to include you in their conversation. However, if they disagree with what you are saying, they remain quiet. It only means that they consider it impolite to argue further.
