A young filly appears in Applejack's life. It wouldn't matter that much if that young filly didn't pretend to be Applejack's daughter. Applejack tries to deal with her own emotions while facing that young filly, when Twilight tries to figure out who the filly is and where her real parents are.
But some other ponies begin to be implicated in a story that is, in fact, way simpler that it could seem at first sight.

Just a thought that crossed everypony's and everybody's mind. A story about what we all want.
And how hard it is to get it.

Sweetie Belle writes a sentence during class. Just a simple sentence over a simple piece of paper. But soon, that sentence begins to obsess her. As nopony seems to understand her, she begins to run away with the obligation to find out the answer to the question:
"Why would a simple sentence have so much importance?"

A very simple story with a very simple idea.

[Warning: this is an economical and caricatural reflexion without much humor]

Pinkie Pie was just enjoying a sunny day. But an encounter with the cutie mark crusaders and the leftovers of their latest creation lead her to build her own invention, the "Superpinkiastrolophilosothingything".

A pony comes and buys it, which Pinkie Pie accepts because it makes the pony happy and she loves making other ponies happy. But as other ponies come too to buy their own "Superpinkiastrolophilosothingything", Pinkie Pie begins to have some difficulty understanding what's happening and how to control it before something goes wrong...

Even if you could think this text is an economical satire, I have to warn you that this is just the way you interpret it. As for me, I just wanted to write about Pinkie Pie inventing the "Superpinkiastrolophilosothingything" and describe what purpose it had. If you want to be lectured, go see Twilight, that's her domain after all...Silly.

As Twilight visits princess Celestia in Canterlot, she discovers a bookshelf with just a dozen parchments with neither bad nor good stories. She speaks about them with the princess and, one thing leading to another, Twilight finishes by publishing her own story.

But this story isn't so much about Twilight than about the world of published writers and the one of amateurs writers. And how the limit between both can be very thin.

Lula is a unicorn and the best accountant of all of Canterlot. She got her accounting cutie mark long before everypony else. But why does life have to be so ironic? Lula hates being an accountant and just dreams of doing magic spells, which she is just terrible at.

As she try once again to pursue her life dream, ignoring the cutie mark rule, thing slowly but surely get out of hooves...
