Members of groups, in fact, tend to exhibit behavior similar to that of residents. They use public space with abandon, in such a way that, for example, a group of adolescents can choose to play running games in an air terminal. They feel free to indulge in backstage behavior, calling each other by name, yelling at one another across the expanse of the setting, using obscene language and laughing loudly at private jokes. And they express proprietary attitudes. If their numbers are plentiful enough, they may even force others to depart, as when the overflow from a convention invades a city's nightspots.
