Kate Chopin's short story "The Story of an Hour" explores how marriage can limit one's freedom, especially for women in the 19th century. When Mrs. Mallard learns of her husband's death, she initially feels joyful and free from her marriage. However, when she discovers he is still alive, the shock proves fatal for her weak heart. Through symbols of Mrs. Mallard's heart condition and an open window, as well as her independent nature and disappointment at her husband's return, the story shows how much she valued her freedom and independence outside of her marriage. The theme of marriage restricting one's liberty is conveyed through irony and the characters' differing perspectives on Mrs. Mallard's emotional state.
