Discuss the title of the novel 'great expectation'.

My, what big ears you have. What big teeth you have. What great expectations you have. The title refers to Pip’s "great expectations" which are many dimensional and ever-evolving. His great expectations arrive in the form of his fortune and are embodied in his dream of becoming a gentleman. These expectations also take the shape of his longing for a certain cold star named Estella. Each of the three parts of the novel treats a different expectation, and we watch how Pip changes in the face of his changing expectations.
