In "Eleanor Oliphant Is Completely Fine," Gail Honeyman explores themes of loneliness and human connection through the life of Eleanor, a socially awkward woman with a rigid routine. Her interactions are limited, and she spends significant time in solitude, leading to her unique perspective on life. Her occasional conversations with a pot plant raise questions about sanity and the nature of companionship, inviting readers to consider the boundaries between acceptable social behavior and isolation.

The phrase "If a tree falls in a forest and no one is around to hear it, does it make a sound?" resonates with Eleanor's experiences. It highlights the idea that existence and perception are intertwined; something may happen without anyone to witness it. Similarly, Eleanor's dialogues with her pot plant symbolize her quest for connection in a world that often overlooks the struggles of individuals like her. Ultimately, both elements emphasize the significance of understanding and empathy in our interactions with others.
