In Margaret Atwood's "The Blind Assassin," the narrator expresses a deep sense of betrayal regarding the forging of her handwriting by Laura. This act is not just a simple deceit but a violation of personal identity, as handwriting is an intimate reflection of the writer's individuality. The narrator highlights the uniqueness of each person's handwriting, comparing it to a theft of one's identity, which adds to the emotional weight of the act. Moreover, the comparison between the different handwritings—hers and Richard's—emphasizes the personal connection and the distinctiveness of one’s written expression. The narrator believes that Laura's handwriting was easier to replicate, which suggests a deeper recognition of her sister's inner self. This sentiment underscores the theme of authenticity and the boundaries of personal expression, making the act of forgery not just a minor misdeed, but a profound ethical breach.
