Final answer:
In 'The Glass Castle,' Rex Walls grows a beard as a representation of his nonconformity, individualism, rebellion, and the family's financial situation.
Step-by-step explanation:
In 'The Glass Castle' by Jeannette Walls, Rex Walls grows a beard for a variety of reasons that relate to his character and his life circumstances. His beard could symbolize his nonconformity and rejection of societal norms, as he often clashes with conventional expectations and lives a nomadic lifestyle.
Additionally, Rex's beard can signify his rugged individualism and perhaps a sense of rebellion. Growing a beard might also reflect his financial situation and the Walls family's overall approach to personal care, which is often minimal due to their poverty.
