The speaker reflects on the contrasting personalities of herself and her mother. She describes her mother as an ordinary person who is confident and steadfast in her beliefs, though perhaps lacking in empathy. The mother's strong-willed nature is admirable, as she is fully authentic in her approach to life.
In contrast, the speaker acknowledges her own emotional vulnerabilities and defense mechanisms. While she also displays a tough exterior, her bravado is a shield to protect her sensitive nature, revealing a deeper struggle with self-identity and openness. This juxtaposition highlights the complexities of their characters and their differing ways of navigating the world.
