In "Little Bird of Heaven," Joyce Carol Oates explores the theme of identity and the complexity of human experience. The narrative suggests that individuals often adopt facades, masking their true selves with pretense. This reflects a deeper commentary on the nature of reality and perception, highlighting how people navigate their lives by embodying various roles.

The quote emphasizes the rarity of genuine authenticity, suggesting that while one can simulate many traits and emotions, true essence is difficult to capture. This underscores the tension between appearances and reality, and invites readers to reflect on their own identities and the masks they wear in different aspects of life.
