In Tennessee Williams' play 'The Glass Menagerie,' the fragile dynamics of the Wingfield family are explored through the symbolism of the titular glass collection, representing the characters' vulnerabilities and dreams. Tom Wingfield, the narrator, grapples with familial obligations and his desire for independence, while his sister Laura uses her glass unicorn figurine as a safe haven from her insecurities. The play highlights themes of escapism and the struggle for self-identity amidst the constraints of their lower-middle-class existence in St. Louis.
