In literary criticism, the word "epiphany" refers to a moment in which a character experiences a sudden, life-changing revelation about the true nature of something. These moments of insight are usually prompted by something seemingly trivial or commonplace, but they result in a radical change of perception on the part of the character. Consider either James Joyce's "Araby" or "The Dead" and explain how the central character in either of these stories experiences an epiphanic moment.

What does the protagonist learn about himself, about another person, or about life, and how does this experience and gained insight change him?
