In the narrative presented in "The Heart Goes Last" by Margaret Atwood, the characters exhibit a complex emotional expression when they interact with the protagonist. The smiles they offer are not just superficial gestures; rather, they reflect a blend of genuine sentiment and a touch of artifice. This duality indicates that their happiness may be influenced by external factors, suggesting a deeper commentary on human connections and the facades people maintain.

Atwood's portrayal of these interactions emphasizes the intricacies of social behavior. The term "total-face smiles" signifies that while the smiles are radiant and engaging, they may also mask underlying truths about the characters' feelings or the situations they are navigating. This nuanced observation prompts readers to consider the authenticity of joy in interpersonal relationships and the possible hidden tensions that lie beneath seemingly happy exteriors.
