Certain things they should stay the way they are. You ought to be able to stick them in one of those big glass cases and just leave them alone. I know that’s impossible, but it’s too bad anyway.
– J. D. Salinger
The Catcher in the Rye. Chapter 16, Holden is walking through Central Park and strikes up a conversation with a little girl, who suggests that he look at the Museum of Natural History with the Indians in it. He sets off in that direction, thinking of the field trips he took there as a kid, when everything was sweet and innocent, and the museum never seemed to change. Holden simply hates growing up. Part of his depression is the knowledge that his desire to keep things the way they are is impossible.
