In the past fifty years, American society has changed a great deal. Fifty years ago, most Americans lived in small communities. They rarely moved from one area to another and knew their neighbors at least by name if not by close, personal relations. Life was so personal in those days that people often joked about it.They said that a person could not even stay home from church on Sunday without the whole town knowing about it. It was difficult to keep one’s secret in a small community like that, but there was usually a sense of safety, of belonging, and of community togetherness in such places. Except for church and the local movie theater, there was not much entertainment. Some people dreamed about moving to the exciting life of the big cities, but most people were happy to live all their lives in the same community.
