Margo’s notebook is a figure of her developmental processes, and of the growth she has undergone since childhood. Margo fills the notebook when she is a young girl with a story that reflects her dreams, her desires, and her need to see the world as a kinder and more loving place. As she gets older and becomes increasingly disenchanted with her life and dissatisfied with herself, the notebook becomes a place where she escapes from her reality by throwing herself into the work of planning elaborate adventures and schemes and pranks. The notebook is also the place where Margo begins to imagine an alternative life for herself and an alternative way of being, as she begins to plan her final departure from Orlando. Margo carries the book with her at all times, but nobody knows what she uses it for; in this way, it becomes a symbol for the way she keeps her authentic self hidden from others.
