Throughout the book, the narrator's relationship with his father evolves from a traditional, hands-on father figure to a more spiritual and symbolic bond. Initially, the father is a provider and a guide, teaching the narrator practical skills and values. As the father's health deteriorates, the relationship shifts to one of care and dependency, with the narrator taking on the role of caretaker. This evolution reveals the cyclical nature of fatherhood, where roles are reversed and the son learns to honor his father's legacy through memory and reflection.
The book also highlights the profound impact of loss on the individual, showing how the narrator grapples with the absence of his father through nature, particularly the river and birds. This connection to the natural world signifies the enduring presence of the father in the narrator's life, even after death, and underscores the universal themes of life, death, and the continuity of existence.
