laura's personality?

Laura is painfully shy, unable to face the world outside of the tiny Wingfield apartment. She spends her time polishing her collection of tiny glass animals, her "glass menagerie." Her presence is almost ghostly, and her inability to connect with others outside of her family makes her dependent on Tom and Amanda. Jim's nickname for her, "Blue Roses," suggests both her odd beauty and her isolation (a good point) as blue roses exist nowhere in the real world. She is in many ways like Rose, Tennessee Williams' real-life sister. As a parallel to Rose, then, Laura becomes helpless and impossibly passive - rendered to a fate entirely dictated by Tom's own decisions. Laura's passivity, meanwhile, incurs a tremendous amount of guilt and repressed rage in Tom, who has trouble leaving as long as he thinks of his sister.She isn't a bad person, she merely retreats into her own world or the zoo.
