Themes to explore: identity crisis, autonomy vs. control, communication issues, cultural expectations, perhaps even mental health. The title's ambiguity could lead to discussing how the exchange affects their sense of self and each other's behavior.
Need to find examples from the 17 scenes to support each point. Since I don't have the actual text, I have to create plausible examples. Maybe some scenes involve cultural traditions, others personal ambitions, conflicts over career or marriage, emotional revelations, etc.
I should also look for any real-world parallels. Are there literary works that deal with similar themes, like "The Parent Trap" or "The Autobiography of Alice B. Toklas"? Comparing these could provide a richer analysis.
