Final answer:
Goldman thought the reunion scene was left out because it would have contradicted the play's tragic and dramatic ending.
Step-by-step explanation:
Goldman thought the reunion scene was left out of the play because it would have taken away from the tragic and dramatic ending. The play 'The Glass Menagerie' by Tennessee Williams ends with the character of Tom leaving his family, symbolizing a broken family and shattered dreams. Including a reunion scene would have provided a more hopeful and optimistic ending, which goes against the overall tone and themes of the play.
