On the eve of the Coexistence Carnival - one of the most important celebrations in the world, where each and every kingdom comes together one night in peace to celebrate unity - Celestia (and Luna, I guess) accidentally reveals a secret about themselves.

Or, rather, reveals an accidental secret.

Rated teen because of one utterance of the f-word and one utterance of the b-word.

*Edit*
Wow! What a great response! I also went through it and changed a few wrong words here and there, an awkward sentence at another spot. Nothing major.

I can't believe this got featured! Celebration!
