Hexagonal relation 

 
 The catcher is the center of a hexagon, Holden wants to be a catcher in the rye, in a fiction he said he wanted to catch children before they fall out of innocence into an adult world which is filled with phony and sex. For Holden, the mummies mean a no disappeared face, he always worries about he would disappear or be a "faceless" guy. The relation between them are disappearance, Holden doesn't want to children disappear in their "innocence" world, he also doesn't want to "disappear" in the world.
  Baseball "mitt" hints Holden's brother Allie, he is gone in a disease. "The Catcher" doesn't catch his brother successfully, his brother disappears in a cliff. Love innocence is an important factor in a fiction, it's the main reason "the catcher"  catches children, Allie is innocence so "the catcher" wants to catch him. Holden's cynical tone is a major melody of a book.

  The death is a major theme in a book, from the mummies and his brother's death we can connect to Holden's mind. Holden always thinks he would die and what happen after he died, the more he thinks about it,  he feels more depressed and lonely. Holden still felt sorry about his brother's death, that makes his personality changed. At the beginning of the book, when Holden's roommate mocks his brother, Holden feels angry then fights with his roommate. Actually, he blames Holden's article because it is a memory about Allie. The interesting thing is, there are another reason results in the fighting, his roommate dates with Holden's old friend, that makes Holden feels jealous. Throughout a whole book, except his brother Allie, Holden's sister also makes Holden's personality changed. Everytime Holden sees Phoebe, his mood always becomes better, especially at the end of a fiction, when Phoebe on the carousel, Holden feels so happy because he sees an image of innocence.
  According to Holden's cynical view and hatred of adults, when he realized he couldn't find a way to survive in a world, his logical action is escaping from the world, that the reason why he wants to go away from the New York and goes to the West. It's the same action he'd done in his prep school, after Holden fought with his roommate and he found nobody could tell with him, he decides to go away from the school.
  At the end of a book, Holden sees three times "FC U" on the wall, every time he wants to erase it, especially he sees those dirty words in Phoebe's school, he near crazy because he thinks how Phoebe and other kids would see it. It highlights Holden really wants to protect children from phonies and he very hates adults.
