Derpy Hooves was just finishing up her last rounds as one of Ponyville's finest mailmares. She was quite dedicated to her job, and strived to get mail and packages delivered on time no matter what. It was one of the few things she was good at and that nopony could poke fun at her about, because very few of them could ever say they could do better than she. Her cutie mark had nothing to do with delivery it was true; seven bubbles, and she had no memory of the circumstances that had led up to her gaining it, or when.
She was just flying across a field toward Sweet Apple Acres to deliver some mail to Granny Smith. The orchard was on the outskirts of Ponyville not unlike Derpy's little cottage was. In fact, her home wasn't that far because her roommate Golden harvest, or Carrot Top as most ponies called her, had a small carrot farm that helped to bring in bits to pay for bills and the like since Derpy was a single mother and a mailmare's salary sadly didn't allow her to buy all the care her tiny unicorn filly Dinky needed. Dinky was born prematurely and had several medical problems as a result along with her diminutive stature. It was sometimes hard to imagine her having any problems however, what with how outgoing and energetic she was.
Anyway, Derpy was on her way when a strange blue box suddenly dropped out of nowhere. It startled the grey pegasus enough that she fell out of the sky as her wings clasped themselves tightly to her sides. Oh the reactions of a pegasus when they were scared... At any rate, she fell a couple of yards and skidded to a stop with her nose up against the back of the box. She heard talking from a distinctly male voice that sounded like it came from Trottingham; not a common accent in Ponyville except with Pipsqueak and his family, but this one seemed softer, less distinct somehow. Curious, the pegasus dusted herself off and straightened her mailmare's hat and bag before she flew over the box. She was immediately greeted by the sight of a very attractive earth stallion who looked to be quite lost. He mentioned something about going to find somebody around to help him out. Somebody? Derpy hadn't heard that word before.
So feeling obligated to show that ponies in Ponyville were helpful and friendly, she flew right in front of him, though was admittedly looking at him upside down. She had to hold onto her hat to keep it from falling off while her blonde mane, tail, and delivery bag all hung down from gravity.
"Hiya Mister! Are you lost? I've never seen you before!" she greeted brightly.
