Take note of how often Holden chooses to refer to what he does as what “you” do.
When Holden uses “you” instead of “I” or “me” or “myself,” it allows him to distance himself from painful memories. He’d rather believe that everyone feels exactly the same way as he did/does than make himself vulnerable by revealing his own personal emotions.
