Dear Diary,
Rainbow Crash is my new nickname. Everypony hates me here. I can't take it anymore. My only friends are Fluttershy, and Gilda, but even Gilda teases me. I hate it here in Cloudsdale. So much. Fluttershy recently moved to Ponyville, should I move there too?
This is basically the story behind why Rainbow Dash moved to Ponyville in the first place.
