Forever

    The sun came up after yet another sleepless night. Pinkie had never gone a night without sleep, let alone three. However, she was a mare on a mission and she was not going to let this hold her back. A weak hoof reached out and grabbed a piece of paper and the pencil. Rainbow Dash was next on the list.

Dear Rainbow Dash,

I followed you around way too much. It was very rude and unfriendly of me to do that to you. Whenever you would fly away, I would follow. You normally knew when I was around, but there were times that I would just hide in the distance and watch you. It is creepy and I understand that. I'm sorry that I treated you that way. Everypony deserves privacy, and I was not respectful enough to give you yours. You are just so cool though, and I really wanted to hang out with you.

Your friend,

Pinkie Pie

Fluttershy's letter came next. Pinkie's handwriting was beginning to suffer from the lack of food and rest.

Dear Fluttershy,

We never really hung out together. I suppose it's because we don't really have the same interests. Your animals are cute and all, but I like ponies. Talking is what I do and you can't really take that from me. That's why I don't usually come to your house. It's not that I don't like you, I just like to talk to everypony and we never have much of a crowd with all of your animals around. I'm sorry for being insensitive, but that's just how I am. If we ever see each other again, I will make up for it somehow.

Sincerely,

Pinkie Pie

    Pinkie's hooves were shaking and it was getting harder and harder to think. "Only one more left." she reassured herself. This was all she had left in the world and was determined to finish what she started.

Dear Applejack,

You are a very respectable mare. The things that you have accomplished are unmatched by anypony else. You work hard and you treat everypony with respect. I wish I could say the same about myself. I'm just too busy talking and partying to do anything productive. I made up excuses every time you would ask me to come help you on the farm. I want to help, but I would rather do things that are more fun. I'm sorry that you've had to do all of those things on your own, even after you helped me with my silly tasks. I wish you could see how hard I can work, but I may never get the chance to prove myself.

Sincerely

Pinkie Pie

    That was it. Pinkie had expressed her feelings toward each one of her closest friends. She still felt that there was something similar about the letters. She glanced back over all five of her writings to no avail.

    Pinkie sealed up the letters in their own envelopes and marked each one accordingly. Next step, delivery. She walked down the stairs with the letters in her mouth. Only then did she realize how hungry she was. It had been days since her last meal.

    The five envelopes were spat out onto one of the tables. Pinkie turned around and headed for the kitchen, remembering the cookies that the Cakes had left out before their disappearance.

    "That's odd." Pinkie said with confusion. The cookies were gone. She swore that she had seen them there just the other day. "Either somepony is around that I don't know about, or I'm going crazy." She assumed the latter due to the combination of recent events.

    Pinkie finally decided to make a daffodil and daisy sandwich. It was one of Twilight's favourites, and by extension, hers. She walked outside for the ingredients, reminiscing on when she would do this with Twilight for lunch when the weren't too busy. "I miss you Twi." Pinkie said with a tear forming in her eye.

    When Pinkie returned to the kitchen, she located the loaf of bread and began to compose her sandwich. As she was topping it off, she heard hoofsteps outside. She sprinted to the door with as much energy as she could muster up only to catch a split second glimpse of a pegasus flying away.

    The mysterious pony vanished in the blue, but not how you would think. The sky twisted and warped as the pony reached it. The equine silhouette passed right through as the ripples subsided. It was as if the sky had eaten the only sign of life Pinkie had seen in days. She believed that her mind was playing tricks on her. Things like that don't just happen. Ponies don't just disappear either.

    Pinkie was beginning to get worried about her own sanity. She knew what she was seeing but wasn't sure if she believed it. None of it could be explained. Her final decision was to press forward.

    All five letters found their way to their respective home's mailbox. Pinkies quest was complete. She was proud of what she had done. Her feelings were finally out in the open, even if nopony knew it. Pinkie then vowed that even if everypony returned, she would leave the letters. Her friends deserved to know how she felt.

    The walk back to her home drove Pinkie into a very depressed state. If those letters were all she had of herself, then what would she be if she never made those friends in the first place. She was nothing without her friends. They made her who she was. Now that they were were gone Pinkie had nothing left to live for.

    Pinkie walked into the shop. It was once a place of happiness, laughter, and fulfillment. Now it would become her grave. She grabbed a length of rope from the storage closet, tied it to one of the support beams on the ceiling, and stood on a chair directly below. With the noose around her neck, she finally realized what was so similar in all of her letters. The one thing that needed to be said to all of her friends. She figured they would be the best last words she could have. As she stepped towards the edge of the chair. She said it for the first time out loud. "I'm sorry."
