A new princess is arriving! (Not Twilight)

  Rarity was in her boutique, doing the usual stuff. Sewing, designing, and other things that contributes to making garment. Except that she wasn't doing very well, for her mind was only set about being crowned Princess. She kept on squealing (Sweetie Belle was not happy) and clapping her hooves. Then, her lilac phone on her sewing table rang. Rarity stared at it, puzzled. Only pony-mailing, letters and meeting in real life were the only form of communication in the modern days. Rarity had wanted to throw away this phone junk (that's what she calls it) but her parents objected to throwing this momento of their olden days communication. Rarity thought it was perfectly stupid to call the phone that, but she kept her mouth shut, as a lady would not speak of such insults.

   Looking as though she was in pain, the marshmallow pony stretched out a hoof to grab the phone, but decided it would be cleaner to just use her telekinesis. Her horn fired up, and the phone..speaker..thingy... flew to her ear. An elegant and regal voice came from over the speaker. She was able to recognise it at once. " Princess Celestia! How may I help you?" The Princess chuckled, then said," I need you to come over to the Royal Palace at once. I have already informed the other five."

What did Rarity do? She went straight, of course. She would always obey royalty!

  " I'm...here.." Rarity panted, sweating from head to hoof. Applejack, Twilight, Pinkie, Rainbow and Fluttershy turned their heads.

  " Hey Rarity!" they called out in unison. Princess Celestia waited for them to be ready, then said," Do you know why I called you girls here?" she asked. They shook their heads. Not even Twilight, the smartest and most observant mare practically the whole Equestria knew, could figure out why her mentor called them here. Princess Celestia continued," It is because you are the only ponies I can trust to tell you why we needed another princess. Ponies from everywhere have come to me, and they are always complaining about tax extension and other problems. So far, I've been getting a hundred and over ponies coming over to me everyday, basically saying 'you are the worst ruler ever'. I will not forfeit my position as Princess of Equestria, but will need another princess to keep the running of this country stable. I do not make the decisions myself, and will take advice from the other princesses. We can only hope that this new princess will be wise and not so immoral." The six looked at her, with their mouths wide open. So this is why she chose such an absurd decision, which was not absurd at all, now that they knew what was going on.

  " But Princess, you don't just choose from the mares who sign-up, do you? They will have to go through many tests, right?" Twilight asked. Celestia nodded, saying," Yes, they do. We will test their wit, patience, and many more, but this only is taken out to those who seem to be of age and have no impure reasons. I'm aware that Rarity has signed up, and I'm sorry to say that you are not one of them. Your reason is invalid." Rarity nodded, and tears welled up in her eyes. She managed to hold them back, but they almost started pouring down. Celestia placed a hoof to the mare's chin, and said," At least you can still be with your friends. Being a princess does not only mean wearing a shiny crown, but also a lot of work. And you do like your friends, don't you?" Rarity nodded again. She never thought about that, and now she felt relieved she wasn't chosen. She looked at her friends, and gave them a great big hug.
