The quote from Susan Cooper's "The Selkie Girl" emphasizes the innate instinct of wild creatures to return to their natural habitats. It suggests that regardless of circumstances, a creature's true nature drives it to seek freedom and authenticity, reflecting themes of belonging and identity. This notion resonates with the idea that even when faced with the comforts of domestication, a fundamental connection to the wild remains unbroken.

This assertion mirrors broader themes in literature and life, where individuals may feel drawn to their origins or roots, regardless of their current status. Such narrative elements highlight the struggle between conformity and the intrinsic desire for liberation. The quote encapsulates a sense of longing for the untainted essence of one's true self and environment, reminding readers that some instincts are impossible to suppress.
