Johnny leaves Ponyboy a note in the copy of Gone with the Wind that Johnny gives to Ponyboy. Johnny, who knows he is dying, tells Ponyboy that he doesn't mind dying now because he saved several children in the church fire. The saved children's parents have come by the hospital to thank Johnny. He writes about the poem that Ponyboy read to him--Robert Frost's "Nothing Gold Can Stay," and compares being young to being gold. He says that Ponyboy has many aspects of being gold, or appreciating the world. For example, Ponyboy loves sunsets. Johnny tells Ponyboy to keep this quality of innocence, and tells him to help Darry appreciate these forms of innocence as well. He also tells Ponyboy to help Darry see the good in the world (as Darry doesn't), and he tells Ponyboy that he doesn't have to be a greaser his whole life but can be anyone he wants to be.
