What is Tom's dual role as narrator and character in "The Glass Menagerie"?
Tom's role as both narrator and character is an interesting one. Tom is the most appropriate to tell the story of his family because he is the one who is finally able to break free from the rut that he was in. Laura and Amanda have not broken free and probably won't, in my opinion. Tom can tell the story with a clearer picture of what living with Amanda and Laura was like because he seems to be the only character who is a tad more rooted in reality and is finally willing to leave the oppressiveness of his home with his mother and sister and find out what it is like to be alone.
I'm not sure exactly what you would like to know about his dual role, but you can find some information on this website's study guide at the following link :
It discusses his dual role towards the bottom of the paragraph, explaining how he is retelling the events that transpired that night before he left the house for good. However, though he has achieved physical detachment, emotionally speaking this evening and its events still linger in his mind.
