Of course you're you, who else could you be? And of course you've just finished reading a story. You're just not entirely certain what the point to the story was, however. For one thing, it was an emotional rollercoaster with a strange ending. You suppose the ending was happy enough, although a deus ex machina is a rather lazy way to wrap up a story.
But the really unusual part was all of the philosophy. You wonder if the author has her head all the way up her posterior, or maybe the whole narrative was designed to convert you to some kind of cult. Then again, maybe it's just a strange story, and it doesn't matter what the author thinks as long as you enjoyed the ride.
Granted, you're not sure how much you enjoyed the ride, but you were definitely there. You might remember it like a story, but you're pretty sure some part of you was with each one of the characters, experiencing what they were experiencing, in all its joy and agony. What if there truly weren't a guarantee you'd make it back here? The possibility is unsettling, but maybe it isn't that bad of an idea. At least in some small way, being other ponies today has become a part of what makes you who you are.
You briefly wonder if Star Swirl was right. Perhaps it wouldn't have been such a bad thing if the ending weren't happy, because you still could have felt something and learned something. A story can be good even if the ending is bad, because the goodness is in the change it evokes in the read—
No, wait. That's ridiculous. This is all ridiculous. Author Tract, Needs Work, Do Not Recommend. Let's shelve this self-aware garbage under 'I read it' and move on.
Still... even after being shamelessly teased by the author, you think you might be up for another story on Fimfiction soon. After all, you have places to be, and sometimes they'll be worth the trip.
And that's okay, even though you'll rarely know exactly where you're headed next.
