The next morning, soon after realizing how hard it is to be an adult, Holden called his old friend Sally Sally Hayes, and arranges a date, but only to have some companionship. Before Holden heads to meet Sally, he stops to eat at a little diner, where he meets and talks to two nice nuns. He desperately tries to show kindness, by donating money for their charity and offering to pay for their meal, which they decline.
Let me pay for your meal.
Holden finally meets his good friend Sally, and takes her to see the Lunts at the theater, where she runs into someone who she knew from school. After the many intermissions and Holden becoming annoyed with this new guy, and everyone else for that matter, they left and decided to go ice skating at Radio City. They had a wonderful time, especially when Sally got to wear the skirt she wanted to try on. But it didn't end so well when Holden, wanting someone to just show him love and care, reacted very rudely towards Sally and just walked out the rink leaving Sally there.
Holden becomes bored and has nothing to do, so he decides to see a movie alone, and thinks about his younger brother, who he misses so much since his death, but he loved the drummer in the Radio City pit orchestra. But Holden is alone and doesn't know who to call. He thinks about reaching out to Jane, who he has great feelings for, but instead calls a boy he used to go to school with. Luce agrees to meet Holden, but immediately regrets it once they meet up, because of Holden's obnoxious and ridiculous questions about the past, when obviously Luce is mature now.
Soon Holden needs to see his younger sister Phoebe, because he has no one else he can talk too. He sneaks int his home late at night to find her asleep and his parents gone. Once he wakes her he finds out they're at a party for a while. He and her talk about so much that has been going on since they last saw each other, not soon after does she realize he's been kicked out of school. But they talk and talk, and after she asks him what his plans are for his future he simply recites the lyric, "If a body catch a body comin’ through the rye." and tells his sister he wants to just save save children from falling off the edge of a cliff, mainly so he can save their childhood and keep them, metaphorically, from falling into adulthood.
Once Holden's parents came home, he says goodbye to Phoebe giving her his hunting hat, which to him seems very sentimental. She gives him some cash and he heads off to see Mr. Antolini, one of his old teachers. There Holden has a deep discussion with his former teacher, about what he talked about with his sister, and Mr. Antolini helps him realize that growing up is hard to d, but if you stay in school and try your hardest, you will face these problems more frequently and see that everyone adjusts to the world around them.
You see it's natural to grow up and experience these things.
The next morning, Holden went to find his sister at her school. He sent her a note and waited for her so he could give her back the money she lent him. Once she finally found him at the Museum, after waiting for such a long time, Phoebe begged Holden to take her with him, suitcase in hand and everything. Holden refused and she became angry. He convinces Phoebe to go to the zoo with him, but she was upset the whole way there. While at the zoo Holden tells his sister to ride the carousal, and while she's up there he loves the sight of her enjoying her childhood. It actually makes him feel the need to cry. But Holden learned how important life is and how he should not take it for granted.
