I have written two versions of this story: One is a humanized version (the original) and the other is a ponified version. (The story works even better in the setting of Equestria) I'm not going to describe much of it because it is a short story and anything more than the short description may spoil it, however I would like to explain why the two different versions have different endings. I find Equestria an idealized world, where everything is tied up in neat little bows, (like many imaginary) whereas the human world is a lot more twisted and not as neat and tidy, so I have made the endings different to suit each setting.
