All That David Copperfield Kind of Crap

When Salinger says, "all that David Copperfield kind of crap," he's referring to one of Dickens' stories/characters where David Copperfield doesn't have a strong relationship with his parents and people are constantly entering and leaving his life. Salinger's character in Catcher in the Rye had a lousy childhood and his parents didn't pay attention to him. This is quite similar to Pip in Great Expectations, but unlike in Catcher in the Rye, Pip doesn't have parents; he's an orphan. In both stories, they're use to unstable relationships. When a reader hears a saying referring to David Copperfield and/or Dickens, they can infer that this is the relationship trying to be portrayed. In Dickens' writing, readers are educated on the characters internal thoughts on these types of relationships and situations. Salinger, however, uses a more distant approach and just refers the reader to Dickens instead of elaborating like Dickens does. Salinger stays away from Dickens' "style" by calling David Copperfield's stuff  "crap".
