Catcher Vignette

 Vignettes are a form of storytelling that Holden often uses in his narrative, and they usually reveal something about his personality. For example in Chapter 15, Holden tells a story about a conversation he had with a kid waiting outside of an infirmary, after his  encounter with the nuns.

 Throughout the story, Holden words things to avoid seeming caring or emotional. The way that Holden describes the religion in his conversation ," The thing was, you could tell by the way he asked me that he was trying to find out if I was Catholic ... That kind of stuff drives me crazy," shows us that while he understates his opinion, the fact that religion was a factor in how that conversation played out deeply bothered him. This makes this vignette powerful because of the unusual way that Holden reacts to it.  

 Salinger's use of italics on certain words help to add emphasis to those words by making them more noticeable to reader.
