Mr. and Mrs. Dursley, of number four, Privet Drive, were proud to say that they were perfectly normal, thank you very much. They were the last people you'd expect to be involved in anything strange or mysterious, because they just didn't hold with such nonsense.
Of course, you probably already knew that.
Mr. Dursley was a big, beefy man with hardly any neck at all, but he did have a large mustache. Mrs. Dursley was thin and blonde and had twice the normal amount of neck, which came in handy as she spent a large amount of her time craning over garden fences , spying on her neighbors.
But you probably knew that too. You know all about the tragic story of the young boy who's parents died a terrible death, and was sent to live with his Aunt and Uncle. A lot of you have probably learned about his finding out about magic, and his many adventures that soon followed. You're probably a huge fan right?
Well, what you don't know about the magical world, is that Harry was never completely alone.
Margo Violet Dursley was born to Vernon and Petunia Dursley the same day their son Dudley was born. They were seemingly perfect children, fraternal twins, actually. Margo was always the more intelligent of the two siblings, being the holder of having the first 'firsts', (words, steps, etc.) and was considerably quieter than the other.
At the age of 1, a new baby joined the family and Margo took an immediate liking to him, even though her parents did not seem particularly happy about the new addition. At the age of 4, Harry and Margo were inseperable, Margo protecting Harry from her oaf (even at 4) of a brother. At 6 years old, Margo was shipped off to a boarding school 'For the academically gifted'. At the age of 8, Margo was sent to a different boarding school for the 'Artistically talented'.
On the summer of her 11th birthday Margo came back, Harry and Margo were still the best of friends, Margo helping Harry with his chores and hanging out with each other every day.
And this, is where our story begins.

Margo woke up to the sound of birds chirping outside of her window, specifically an owl. Margo vaguely wondered why an owl would be perched outside of her window in the daytime, but quickly brushed it off as she stretched her aching arms. Sunlight was filtering through the curtains as she had forgotten to close them before she had gone to bed. Harry and Margo has stayed up late talking last night, Harry wishing her a happy birthday at 11:59 according to the clock in her room, Harry always remembered that the shoddy clock in her room was always exactly one minute late. They always wished each other happy birthday at midnight, every since Harry's 7th birthday and Margo and Harry had stayed up later than usual.
Margo glance around her room, quickly locating where she had left her camera, and slipping it around her neck before getting out of bed. Margo's camera could be found around her neck from the moment she woke up, to the moment she got into bed almost every single day. An old polaroid camera, a present from her 7th birthday. Instant pictures covered one wall of her walls almost entirely and she also had a box filled with them. Margo quickly changed into her clothes for the day and exited her room, lightly treading the stairs in case Harry was still asleep. Margo doubted that Harry would still in bed, mom would have woken him up by now.
Sure enough, Harry was stood over the table setting the bacon down when she walked into the dining room. Margo gave Harry a hug and a good morning along with the rest of her family, excluding Dudley as he was about to throw a tantrum about the amount of Birthday presents mum and dad had gotten. Margo rolled her eyes and ate a piece of bacon as Mum promised to buy him two more presents. She gave Harry another piece of bacon off of her plate, knowing her mother hadn't given him much to eat last night. After finishing her bacon, Margo sat down in front of her three presents that she asked for every year. Mum and Dad always set her presents in the corner apart from Dudley's. Harry sat next to her as she began opening her presents. Margo snapped a picture of Harry when he smiled at her. SHe had gotten a new notebook, a series of books, and a new bag to carry her camera and pictures around in.
She got up and gave her father a kiss on the cheek.
"Bad news, Vernon." Mum says, her face grim as she hung up the phone. "Mrs. Figgs broke her leg. She can't take him." Mum's head jerked towards Harry. "What are we going to do?"
Margo smiled, "He could come with us to the Zoo! I never get to have a friend come with us. Harry is my friend." She piped up.
Her mother grimaced, looking at her father for confirmation.
Dudley suddenly screwed up his face and let out a loud wail, "I.. don't.. want... him t-to come!" Dudley wailed between great sobs. Margo scoffed. "He sp-poils e-everything!"
"It's my birthday too, Dudley! I want Harry to come!" Margo argued. This was a rare occasion as Margo rarely asked for anything from anyone. She rarely spoke in the first place.
Everyone was slightly taken aback from Margo's outburst, the room was awkwardly quiet until the doorbell rang. "Oh good Lord they're here!"
