Question

What does Tennessee Williams hope to prove in his play The Glass Menagerie?

Answer 1

I don't think he is out to "prove" anything - just make some points and he lets you decide what to do with the story.

Like the girl everyone dismissed. She has strong feelings. People ignore her because she acts differently. They cannot see who she is or relate to how she feels.  

Answer 2

Tennessee Williams is long dead, so what is there to prove?  The Glass Menagerie, in my opinion, is a boring play.

Answer 3

Everything fragile isn't necessarily breakable, beauty is truly is in  the eyes of beholder, present doesn't dictate future, and no lady is an old maid.
