Statuses are marvelous human inventions that enable us to get along with one another and to determine where we "fit" in society. As we go about our everyday lives, we mentally attempt to place people in terms of their statuses. For example, we must judge whether the person in the library is a reader or a librarian, whether the telephone caller is a friend or a salesman, whether the unfamiliar person on our property is a thief or a meter reader, and so on.

The statuses we assume often vary with the people we encounter and change throughout life. Most of us can, at very high speed, assume the statuses that various situations require. Much of social interaction consists of identifying and selecting among appropriate statuses and allowing other people to assume their statuses in relation to us. This means that we fit our actions to those of other people based on a constant mental process of appraisal and interpretation. Although some of us find the task more difficult than others, most of us perform it rather effortlessly.

A status has been compared to ready-made clothes. Within certain limits the buyer choose style and fabric. But an American is not free to choose the costume of a Chinese peasant or that of a Hindu prince. We must choose from among the clothing presented by fit, as well as by our pocketbook. Having made a choice from minor adjustments, we tend to be limited to what the stores choice among them is limited.
