The Life of Pi tells the story of a young boy who finds himself as part of a "journey" which he takes with someone (a Bengal tiger) who challenges him to "grow up" as a part of his survival. He tells the story in a sort of retrospective tone, so he looks back on his childhood and adolescence. In GE, Pip also looks back and tells about the ways in which he grows up and some of the "delusions" he has in that growth. Ultimately, as an adult he has to face that his adolescent expectations about Estella and Miss Havisham are completely blown away as he learns about Magwitch, Jaggers, Molly, and Compeyson. He certainly learns that what we learn as children and young adults are not always the whole truth.
