In "The Glass Menagerie," Williams develops the themes as follows:
1. Facing reality is better than living in a fantasy world:
- Laura spends her time playing with her glass animals instead of practicing on the keyboard.
2. Concealing one's feelings can put a strain on relationships:
- Tom keeps his plan about joining the Merchant Marine from his mother.
- Jim doesn't tell Tom that he's engaged to Betty and will be getting married soon.
These details from the text illustrate how Williams explores the themes of facing reality and concealing feelings through the characters' actions and choices. Laura's retreat into her glass menagerie represents her escape from the harshness of reality, while Tom's secrecy and Jim's withholding of important information highlight the consequences of concealing feelings on relationships.
