What is the author's style in The Glass Menagerie by Tennessee Williams?

Although most plays do not rely on a narrator, The Glass Menagerie is structured so that Tom can fulfill two roles. He is both a character in the play and the person who, at times, tells the story directly to the audience. This occurs particularly at the beginning of the play, when Tom summarizes the events that have preceded the action and describes the setting, and at the end of the play, when Tom reveals what has happened to him during the intervening years.

Most of the action in The Glass Menagerie occurs over only a couple of days, nearly every scene is laden with overt conflict. The most obvious conflict occurs between Tom and Amanda, since Tom needs to remove himself from the family in order to achieve his goals, while Amanda needs him to stay. This conflict is most evident during their frequent bickering about the way Tom chews his food or the number of cigarettes he smokes. A more significant conflict, however, occurs within Tom's character. In order to follow his dream, vague as it is, he will have to abandon not only Amanda but also Laura.
