People express their personalities in their clothes, their cars, and their homes. Because we might choose certain foods to “tell” people something about us, our diets can also be an expression of our personalities. For example, some people eat mainly gourmet foods, such as caviars and lobster, and they are only in expensive restaurants (never in cafeterias or snack bars). They might want to “tell” the world that they know about the “better things in life.”
