Love makes you sacrifice the most valuable things in life. In the short story, “The Gift of the Magi” by O.Henry, the author uses characterization, mood, and irony to convey the theme in numberless ways to express the feeling of love and sacrifice.O.Henry uses indirect and direct characterization to introduce the reader to the main character, Della. As cited in the story, Della is a warm, loving, poor girl who cares deeply for Jim, and with only a $1.87 saved throughout the year, she sacrifices her most prized possession, her hair. Although Della does not have much money, she saves whatever she can because it is important for her to find a nice gift for Jim. This shows us that Della puts Jim before herself. Through the use of characterization, O.Henry conveys the theme and empowers the reader to connect to Della and acknowledge the love and sacrifice she shows for other people.The author uses the mood of the story to influence the theme by expressing a feeling sympathy through the author’s diction, and Della’s and Jim’s actions. The mood of this story is very affectionate because you realize how much Della and Jim love each other. You can tell that they are willing to sacrifice anything for their love.Finally, O. Henry uses irony to develop the theme of the story by presenting us with two characters who generously sacrificed their most prized possessions in order to purchase Christmas gifts that the other would be excited about receiving. As cited in the text “Della cuts and sells her hair to buy Jim a chain for his watch, and Jim sells his watch to buy Della combs for her hair.” Even after they tell each other that they cannot use their gifts at the moment, they still are thankful for the effort and keep a positive perspective. In conclusion, the use of characterization, mood, and irony clearly promote the author’s idea of how love and sacrifice is more powerful than expensive offerings.
