How did phoebe influence the story

She asks Holden for one thing that he likes a lot. He thinks of two things. The first is the nuns at Grand Central. The second is a boy at Elkton Hills named James Castle, who had a fight with. Finally Holden confesses to Phoebe that he would like to be a catcher in the rye: he pictures a lot of children playing in a big field of rye around the edge of a cliff. Phoebe is able to get through to Holden on an intimate level. While Holden hides behind the “phoniness” and hypocrisy of the world in order to not appear vulnerable or exposed, Phoebe is able to let Holden’s guard down. Holden loves Phoebe’s innocence and, above all, he loves his little sister.  His relationship with Phoebe prevents Holden from becoming completely detached from the world.
