What do johnnys last words to pony mean?

Answer 1

well later on in the book, Ponyboy finds a letter in the book Gone with the Wind and it said that he was gold meaning he wasn't like any other person. he was his own self and he never followed what others did. he looked at the other side of the situation and he wasn't a big juvenile delinquent. basicly, he told him to be himself and show others that its okay, like showing dally the sunset

Answer 2

Johnny tells Pony to stay gold.... from the poem in gone with the wind.

and johnny means not to change himself over anything or anyone. just be your self and don't change!
