The Dursley family of Number 4 Privet Drive was enjoying a quiet day when Vernon Dursley asked, though it is a relative term, his nephew Harry to fetch the mail. To Harry this was an everyday occurrence but what he didn't know was how wrong he was to consider today ordinary. A letter was waiting for him. It wasn't the usual bills or newsletters but a chance, a chance to escape the "care" of the Dursleys.
When he first saw his name on the letter, he had to clean his glasses and see again to believe his eyes. He secretly stuck the letter inside his pocket and gave the rest to his uncle. Contrary to the beliefs of the Dursleys, his teachers and the neighbors, Harry was not the less than mediocre boy who he seemed to be. He was actually very perceptive for his age and he figured out soon that performing well would get him beaten everyday at the hands of his uncle and cousin Dudley. A letter for him could easily find itself in the fireplace if his uncle saw it.
Flashback:
He was 6 years, running from his cousin and his friends who were enjoying their favorite pass time: Harry Hunting, when he stumbled upon a library occupied by an old man. That man had a white beard long enough to reach his waist and looked old enough to be around the time the Great wall was built. There he found a place where he could always find a safe haven from his cousin. The man, who he grew to call a friend and mentor, showed him various books and techniques to calm and organize his mind in various segments which he had imagined as a house with different rooms for different types of memories. There was a room for happy memories, one for sad memories, one for the memories of Dursleys and so on. This exercise of his improved his memory a hundredfold giving him a nearly perfect recall. Another thing that he realized was that if he ran fast enough Dudley and his friends would soon give up trying to catch him, so naturally, a fitness regime found its way in his daily practices. His improved fitness also resulted in him learning basic self-defense from his mentor.
Harry made his way to his cupboard to see who would write to him and why. He picked a pen and paper swiftly in case he needed to respond to the letter. Reading the letter, his mind trailed to times when his family called him a freak and the strange occurrences around him. He figured that either the Dursleys were playing a prank on him or he truly held unimaginable power in his hand. Since his family despised such actions as they were beneath their standing, only one thing made sense, he truly was a wizard.
Harry had already finished all his daily chores so a sudden call from his aunt was not to be feared. He immediately started writing his response. He decided that everyone would expect a clueless boy asking for advice and he was going to give them just that.
Dear Professor McGonagall,
I thank you for the invitation to your school. I, at first, found myself confused regarding the existence of magic. But I do admit that I have noticed strange occurrences happening around me. I request you to send someone to assist me so that I can familiarize myself with the magical world. This will also provide me with a definite proof of the existence of magic.
Thanking you
Harry James Potter
Harry read the letter again to make sure it was perfect. But now he realized he didn't know how to send it. He quietly opened the cupboard's door and went to a window sill. He thought of posting it the normal way but soon dropped the idea realizing it's stupidity. He had the response as well as the acceptance letter in his hand. He suddenly got the idea to put the response in the envelope of the original letter thinking why not? As soon as he had reattached the seal that was in the shape of a crest back to the envelope, an owl came swooping down to the sill and put his leg forward as if asking for the letter. Owls and letters, Harry thought, must be a wizarding tradition. He presented the letter to the owl who snatched it up and flew away as if already knowing where to drop the letter.
Now, the only thing Harry could do was wait. He hoped that the letter reached its destination and that too quickly. He knew this was his chance to a good life. And it would take the Satan himself to keep him down from fighting for it.
