Twilight never said much - if anything at all - as she stood, puffy eyed and with tear drenched cheeks in front of five graves all lined up one beside the other up on a hill in Sweet Apple Acres. Rainbow was the first one to leave the world and before she did, she requested that she be buried somewhere other than 'some gloomy old cemetary'. So they found the perfect place for her on an empty hill overlooking the entire orchard.
After that, when each of her friends' times came, they all wished to be buried next to each other. Rarity had said that they were 'making a statement' and it was that even Death could not part them from each other.
One of the graves though, were still fresh. Twilight stood in front of said grave, having been notified early in the morning about what had happened.
She knew the day would come but was dreading it with every fiber of her being, but even Celestia herself couldn't stop it from happening. When she heard the news, her brain came to a halt. "Ms. Pie passed away last night in her sleep." That very sentence broke her, for minutes which felt like hours on end she did not move and when her brain finally started working again she completely broke down. She had missed the funeral in the time it took for her to compose herself enough to be able to leave her room, but she didn't care. She wasn't there for the condolences or the speeches, she just wished she could have gotten to say goodbye.
After a few minutes she heard a slight flapping followed by hoof-steps behind her, turning to see who it was she saw an equally puffy eyed and breathless Pound Cake behind her.
"Miss Twilight, I'm sorry to barge in on you but when I heard you were here I knew I had to get this you to you." Opening his bags and handing her a letter, he continued, "We found this on her desk when we went to wake her up for breakfast."
She took the letter from him wordlessly with her magic, offering a nod and a small smile in thanks. He returned her actions and then turned and took his leave. Turning back to Pinkie's gravestone, she levitated the letter in front of her, opened it out and began reading.
Hiya Twilight!
I figured I'd write this little letter because I sincerely doubt I'd be able to tell you all this myself the next time you come to visit, and I don't want to disturb you right now since you might have some important royal thingy to attend to.
I never imagined me lasting as long as I did, you know, I always thought i'd be the first. But you girls always said I was full of surprises and that you hoped I'd never change well, wish granted! I've lived a good, long life with very few regrets. Which is why I wanted to write this in the first place, Twi. I wanted to thank you and Spike. For the memories, good and bad; for those crazy-awesome adventures we went on, sometimes testing us and we would only come out of it with our friendship stronger than ever.
There are very few things I truly fear, Twilight. You know me enough for that, you might even say that I have no fears and far as you know, that's true. The list of things I fear is very short but you wanna know what's at the top of that list? It's living in a version of Equestria where this adorable little bookworm and her dragon never stepped hoof inside Ponyville. That pony who brought us all together and started a friendship that was destined to happen and would survive anything thrown at it. ~~Of course, directly below that is living is a world where ponies don't like parties or where there is no existence of cakes and sweets! I mean can you imagine living without~~ Sorry, ignore that.
So there you have it, you always did wanna know what my greatest fear was. I remember our first time actually meeting, me sneaking into the library and setting up that surprise party for you. Oh how you must have despised my pink cushy little cupcake devouring guts. I mean, I knew you weren't all that happy about it but I was hoping you'd come around, so I stayed and boy, am I glad I didn't give up on you! I mean I used to see the others around town every now and then but I don't think Dashie liked me very much, whenever i'd show up out of nowhere she'd say she had somewhere to be and if it wasn't for you, we'd never have gotten so close! I know Rarity and AJ would never have even spoken to one another more than they even needed to and poor Fluttershy would stay locked up in her cottage all day!
You changed all of our lives just as much, or even more than we did yours! And all for the better, no doubt about that. Now, if our friends' times were anything to go by, you're probably weeping your pretty little eyes out over me. But I don't want you to do that, Twi, so put on a brave face for your Auntie Pinkie Pie. Remember how I told you to giggle at the ghosties? Well, by the time you read this, i'll be a ghostie too, Twi. A pink, goofy, giggling ghostie completely overjoyed that i'd get to see the rest of my friends and be with them again, and you'll get to see all of us again too! I'll be watching you so I want you to try and giggle with me, Twilight. Giggle with me, Dashie, AJ, Fluttershy and Rarity. Laugh at all the times we played pranks on each other, joke about all those times Dashie joined us at the spa despite saying she hated it [She'll get me for that one, i'm sure].
The way I see it, Twilight, is that our lives are a pile of good things and bad things. Now, the good things don't always soften the bad things but, vice versa, the bad things don't necessarily spoil the good things or make them unimportant. So as long as you hold on to all the good, you'll be oki doki loki!
So even though it'll be super-duper hard... my one, last wish is this: Try not to be a Frowny McFrownypants for me because we're all still gonna be here. We'll wait for you, Twi even if we have to wait forever, because that's how much time we have and because that's what true friends would do. We'll wait for our adorkable Princess and her baby dragon, even though Spikey-Wikey'll be a very, very big baby dragon by that time. We'll wait for the spark that brought us all together, when the Elements of Harmony will be together again. I'll even make sure to have a special party planned just for you and Spikey when we see you.
But, I think I can hear Dashie calling me now, the girls have been talking to me for a while now in my dreams, they've always sounded so happy but I know I can't be dreaming right now. They ask me to tell you to stop worrying so much over them, because they're happy and you should be too. Because you deserve to be happy just as much as the rest of us, Twi and you must never forget that. I know how you can be such a silly pants and overwork yourself or how you can forget things now and then.
So I guess that's it, Twi. I hope I haven't forgotten anything important, but i'm starting to feel really tired now, I think i'll go lie down just to rest my eyes for a moment.
Goodbye, Twilight Sparkle.
Goodbye, Spike.
And no matter happens, remember to Smile, Smile, Smile!
~ Pinkamena Diane Pie.
She could do nothing but let her tears flow as she read the letter Pinkie left for her. She tried to smile, but everything she could think of that would normally make her laugh, was doing the exact opposite to her. She wasn't sure how long she lay there, but she started to notice the sun setting. She was in too much a hurry to wait for her guards when she left and now she was too exhausted to fly all the way back to Canterlot.
She started making her way down toward the Apple's house, hoping that Apple Bloom wouldn't mind housing her for the night. Looking back as she reached the bottom of the hill, a gentle breeze passed by the area and she could have sworn she heard the laughter of one very specific pink pony accompanied by that of a cyan daredevil originating from the spot she just left. She could have just been imagining it, but either way it brought a small smile to her face.
The day would come when she saw her friends again, where they could live together for all eternity and she awaited that day with not a trace of fear, for as long as she had her friends there was nothing she couldn't do.
If the ponies we love are stolen from us, the way to have them live on is to never stop loving them. Buildings burn, ponies die, but real love is forever.
Author's Note
Well, go easy on me guys! When this idea hit me, I was in a pretty crappy mood and combined with my brilliant writing skills, I fear to predict how the story may be received.... Hopefully well! 
The quote that is used at the end is this one:
"If the people we love are stolen from us, the way to have them live on is to never stop loving them. Buildings burn, people die, but real love is forever." ~The Crow, written by James O'Barr, David J. Schow, and John Shirley, 1994.
