Catcher in the Rye

…

…people rise to the occasion and become adults. Some people just realize that they are old enough and should start taking responsibility for their actions. In the end, everyone, even Holden, must become mature. However, during the time that takes place in the novel, readers have only begun to see hints that Holden will transform in a more mature person. He has not transformed yet, but without maturity, one cannot survive in the real world.
