The Catcher In The Rye?

Question:

The Catcher In The Rye?

I just finished reading The Catcher In The Rye for my English class next fall, and i thought it was a great book, one of the best I've ever read. I just wanted to make sure i got the meaning. Is it that Holden cherishes innocence and wishes that he could have kept his own. And being in a world full of phony people, he wishes to save the children 'in the rye field' from becoming phony adults.
Also i dont understand the last lines in the book..."Don't ever tell anybody anything. If you do you start missing everybody."
Does he mean that once you tell somebody something important, life changing even, you wish that you could take it all back, that you could have the same relationship with them as if they didn't know, as if to pretend it never had happened?

If somebody could help me on this, it would be greatly appreciated...Thank You!

Best Answer - Chosen by Asker: I think that your analysis is perfect. I agree with the one answer that reading is subjective. A million people could read the same story and each and every one of them could come away with a diffrent meaning for the book. I think you have a good grasp on the last line. In fact I never thought of it that way before. As someone who is studying to get her masters in English Literature I love the fact that you read this book and it made you think and you came away with your own conclussions and not simply what someone told you to say. It made you think.
