In "Persepolis," Marjane Satrapi shows how Marji's talks with her grandfather reveal the theme of being disappointed with one’s background and the tricky nature of social and political identity. When Marji discovers that her grandfather was a prince, she feels really excited and proud at first. But her grandfather quickly says, "But that's not the question," which makes it clear that being a prince doesn’t really matter when there’s so much pain and injustice that came after their family lost their power.
Satrapi uses words to show how innocent Marji is and how she romanticizes her family's past. The way Marji looks, with her wide eyes, emphasizes her youth and the shock she feels when she learns about her grandfather’s real struggles. The difference between her initial excitement and her grandfather's serious attitude highlights how disconnected she is from the harsh truths of history.
This idea is a key part of the overall message in the book, where Marji’s journey to adulthood is marked by her growing understanding of the world’s complexities and contradictions. As she learns more about her family’s history and Iran’s political issues, she starts to realize that her identity is linked to both privilege and suffering, which leads to a loss of innocence that runs throughout the story.
