who are cheery

Cherry Valance is a redhead Soc girl, Bob's girlfriend, whom Ponyboy meets at the drive-in when Dally is bothering her and Marcia. In their first one-on-one interaction, Ponyboy realizes how much principle means to Cherry: "Cherry had said she wouldn't drink Dally's Coke if she was starving, and she meant it. It was the principle of the thing. But Marcia saw no reason to throw away a perfectly good, free Coke."
