Whose story is told, and whose is not?

The important story that is told is Holden Caulfield's story. As the main character and the character from whose point of view the story is told, his is the one that should be told. His point of view obviously warps some of what the reader is told; we tire very quickly of his teenaged whining. We recognize that he reacts to such problems as his brother's death and his other brother moving away, so we do not know "their" stories. We really are focused on Holden, so none of the other stories will be told.
