| Americans usually consider themselves a
friendly people. Their friendships, however, tend to be shorter and more casual
than friendships among people from other cultures. It is not uncommon for
Americans to have only one close friend during their life-time, and consider
other "friends" to be just social acquaintances. This attitude probably has
something to do with American mobility and the fact that Americans do not like
to be dependent on other people. They tend to "compartmentalize" friendships,
having "friends at work" ,"friends on the softball team", "family friends",
etc. Because the United States is a highly active society, full of movement and change, people always seem to be on the go. In this highly charged atmosphere, Americans can sometimes seem brusque or impatient.
