The Catcher in the Rye Chapter 26 Summary

"That's all I'm going to tell you about," Holden says, which means we're starting the last chapter much as we started the first.
He says he's not going to talk about how he went home after that, how he got sick, and what school he's going to go to next year "after [he gets] out of here."
He says there's one psychoanalyst around who keeps asking if he's going to apply himself next year – how should he know?
D.B. is there at the moment, too, having driven up along with an English woman in order to see Holden.
He asks Holden a lot of questions, but in particular what he thinks about all this business (the stuff we just read, basically).
Holden doesn't know. He does miss everyone he told us about, even jerks like Stradlater.
That's the thing, Holden concludes: "Don't ever tell anybody anything. If you do, you start missing everybody."
