Who am I then? Tell me that first, and then, if I like being that person, I'll come up; if not, I'll stay down here till I'm someone else.
"Who am I then?" is a reflective question about self-identity, emphasizing the importance of understanding oneself. The speaker seeks confirmation of their current state or personality, indicating a desire to accept or reject their existing self.
The quote suggests that if they like who they are, they will rise and embrace that identity; if not, they prefer to remain unnoticed until they become someone they are satisfied with. This highlights a theme of self-discovery and the fluid nature of personal identity, as explored in Lewis Carroll's works.
