This scenario reflects a focus on life reflection and the desire to leave a legacy, which aligns with the theme of achieving a sense of integrity in later life. Erikson's stage of Integrity vs. Despair is about evaluating one's life and feeling a sense of fulfillment versus regret, and Eunice's action indicates she is looking back at her life in a positive way.
