What does Johnny say about dying?

Johnny says he doesn't want to die.... he's only sixteen.

"You want to know something, Ponyboy? I'm scared stiff. I used to talk about killing myself..." He drew a quivering breath. "I don't want to die now. It ain't long enough. Sixteen years ain't long enough. I wouldn't mind it so much if there wasn't so
much stuff I ain't done yet--- and so many things I ain't seen. It's not fair. You know what? That time we were in Windrixville was the only time I've been away from our neighborhood."
