The play is replete with lyrical symbolism. The glass menagerie, in its fragility and delicate beauty, is a symbol for Laura. She is oddly beautiful and, like her glass pieces, easy to destroy. The fire escape is most closely linked to Tom's character and to the theme of escape. Laura stumbles on the escape, while Tom uses it to get out of the apartment and into the outside world. He goes down the fire escape one last time at the end of the play, and he stands on the landing during his monologues. His position there metaphorically illustrates his position between his family and the outside world, between his responsibility and the need to live his own life.
