Summary of ch. 7 :

Holden talks for a while with Ackley and then tries to fall asleep in the bed belonging to Ackley’s roommate, who is away for the weekend. But he cannot stop imagining Jane fooling around with Stradlater. He wakes Ackley and talks with him some more, asking whether he could run off and join a monastery without being Catholic. Ackley is annoyed by the conversation, and Holden is annoyed by Ackley’s “phoniness,” so he leaves. After passing a few days there in secret, he will wait until his parents have digested the news of his expulsion before he returns to their apartment. He packs his bags, dons his hunting hat, and begins to cry. As he heads into the hallway, he yells “Sleep tight, ya morons!".
