Who I would cast:
Ponyboy- Nicholas used to grease his hair, and you can never really tell what he's thinking
Johnny-Tim because he's somewhat quiet and he is smaller.
Dally: Matt p.because he can be tough but he's still an overall goofball
Darry: my brother because he's really protective and always tells me to not make educational mistakes that he did
Sherri: shiva because she is caring and is very relatable but states her opinions when she wants to
Two-bit: Matt t. He's always joking and sees the lighter side of things
Soda: Ashyan because he's always happy ( except for the fact that ashyan is a great student)
