It's all good in the first section of Salinger's classic story—until he turns things on their head and transforms his narrator into his polar opposite, unable to hang with anyone and possessing the emotional capability of the bluntest rock on the mountainside.

Your task is almost as high and wide as said mountainside, as you've got to get the class up to speed with the huge shift between the first and second sections of the story. Sure you could let the students figure it out all by themselves, but this could be almost as bad as X trying to write a letter to his friend in NYC, an endless struggle resulting in misery, frustration, and disappointment. As well as a lot of wasted paper, which we're not fans of at Shmoop: this could be used for brainstorming, ideology, short stories, novels, and epics, or even just some funny doodles. To each his/her own.
