It is worth noting that people in the U.S. tend to keep considerable space between themselves and those with whom they are speaking. In some cultures, people frequently stand very close to each other, but that may make many U.S. citizens uncomfortable. If you find that someone backs away from you as you talk, it is not a sign of rudeness, nor an indication that they wish to end the conversation. Instead, they are just trying to reestablish a distance with which they feel comfortable. Social Interaction Casual acquaintances are easily made, but just as easily lost.
Close friendships require considerable effort.
They result from repeated interaction between people and the sharing of mutual interests and activities. The key is to participate in informal conversations. Do not let any insecurity about your language ability hold you back. The more people you meet and talk with, the more likely it is that you will find someone who will become a close friend. Etiquette People in the U.S. are very concerned with personal cleanliness.
