The quote from Roald Dahl's "My Year" reflects on the nature of secrets and the profound impact they can have on an individual. It emphasizes that secrets only exist in the absence of disclosure, suggesting that keeping a secret can be a heavy burden. This particular secret is described as the most significant the author has ever had to bear, indicating its importance and weight in his life.

Dahl's reflections suggest that the act of keeping a secret can deeply affect one’s thoughts and emotions. The struggle with such a secret can lead to introspection and a desire to share one’s burden, highlighting the complexity of human experiences and relationships. The quote ultimately underscores the notion that some truths, though deeply personal, can shape one’s journey profoundly.
