Isn't Ending Any Time Soon
You were somewhat of a miracle to your family. Your mother, Twilight Velvet, said that you fell down from the heavens as a choir of angels sang you into her hooves. Of course you didn't believe half of it because she always dramatic in both her sentences and her books.
Your dad's explanation was more believable, saying that you fell into one of their bushes and they thought you were some neighbourhood cat and were about to shoo you away when your head peeked out of the bushes. He said that after that everything happened so fast that the next thing he knew, he had an eleven-year old son from another world! Then he'd laugh and say that he was still proud of calling me his son, after all you were one of the most famous inventors in all of Equestria.
