In the quote from Margaret Atwood's "Cat's Eye," the speaker reflects on a sense of self-doubt and alienation. They perceive their peers as fully formed adults, while they feel like an imposter, merely pretending to be one. This highlights a common human experience of questioning one's maturity and authenticity, suggesting an internal struggle with identity.

This perspective can resonate with many who feel out of place or inadequate compared to others. The idea of being "in disguise" emphasizes the fear of being exposed and the pressure to meet societal expectations. Atwood's exploration of this theme invites readers to consider the complexities of growing up and the profound impact of these feelings on one's self-esteem and relationships.
