So I'm making a story about Applejack as a filly. She's with her two best friends in the story. I know one is Rainbow Dash, but should the third be Rarity, or somepony else? If It's Rarity, then that would explain why the cutie mark crusaders are friends. But I don't know. What do you all think?

Could somepony proof read my story? It's short and random. Thanks!
