In Alice Munro's "Dear Life," the struggles of the protagonist are conveyed through a profound sense of emptiness and emotional burden. The quote reflects an essential part of his experience, highlighting not only his emotional state but also a deep-seated sense of inadequacy and inability to fit into societal norms. This lack, akin to a deficiency in necessary oxygen, suggests that his challenges are pervasive and perhaps unending.

The weight of this internal struggle shapes his perception of life and interpersonal interactions. Munro encapsulates how these challenges can lead to a lifelong quest for acceptance and understanding, emphasizing the complexities of human existence and the silent battles many endure. This insight adds depth to the narrative, inviting readers to reflect on their own experiences of longing and the quest for belonging.
