I know,sad and gloomy. Bur listen! This has a story behind it:
Celestia had only just gotten her pheonix, Philomena. Not knowing the secrets or cultural ways of the creature, she doesn't know how they live immorly. One day, she finds that Philomena is quite sickly, and tries to treat her, but the pheonix refuses stobournly. Feathers kept falling off her until she walks out Celestia's window, leaving one lone feather floating gracefully toward Celestia, who starts to get emotional.
