J.K. Rowling gave the characters and the background. I just provided the rest.
A/N: First time writing a story. Any feedback is appreciated.
It'd grown cold in the house. The Dursley's had left Harry alone hours before to to a very special occasion. Harry could care less, but as his birthday drew nearer, the remembered nudgings from Dudley talking about the cake at Vernon's office gathering garnered a rumble from his stomach. The chocolate icing raced through his head, tantalizing him as he closed his eyes. Deciding on making food, he stood up from the chair behind Dudley's computer. It would not hurt to use it if he wasn't here.
Stretching his back, he hopped down the stairs to the immaculate kitchen, quickly grabbing a plate from the cabinets. As he opened the fridge for the carton of eggs, a loud knock sounded from the front door. Jumping at the sound, he hit his head on the roof of the refrigerator before regaining his composure and setting the eggs on the counter. Rubbing his head as he walked to the door, he wondered at who would come knocking on an empty house. Peering out the side window, he saw a burly man, wearing giant skins of leather. He towered over the door, though it was hard to tell the height of adults when they all towered above you. Despite being small, he was only ten, turning eleven just this night, not that the Dursley's would bother to fuss about it.
In the man's hands sat a delicious looking cake, exactly what he'd been daydreaming about earlier. Deciding that he couldn't be that bad if he had cake, he walked to the door carefully, hoping to hide the fact from the man that he'd just been watching him secretly.
"Well if it ain't ruddy Harry Potter," he said as the door just began to crack open. "You know, I'm sure you heard a bit abou' me already but you shouldn' be drawin' ideas abou' me yet. Look, I even brought yer cake birthday cake to make up for all missed 'uns."
"Excuse me, but I don't think I know you," said a a rather flustered looking Harry as this strange man claimed to not only know him but his birthdate as well.
"Right o'course. You've just never seen me before. I'm Hagrid. Yer mother's sister must 'ave mentioned me before. Petunia is it?" said Hagrid, a jovial look to his face.
"I don't think so... Are you one of the neighbors? Do you work with my uncle?" asked Harry, his curiosity aroused.
"Come on, Harry! Stop pulling my leg. You ruddy well know I'd never live near no muggles-or work for them for that matter. Not enough space," said Hagrid, a faraway look in his. His attention returning back to Harry, he said quickly, "Well let's get this cake underway! I've got your letter for Hogwarts with me, too. It's just gonna be in one of these pockets." Hagrid started to pat himself down looking for the letter before taking two giant steps into the house. Harry managed to move quickly enough to miss him, but he was starting to get worried. A strange man had just walked into his aunt and uncle's house. He knew Petunia would make him scrub the floors where Hagrid's boots left mud.
Hagrid set off to the kitchen table, taking a seat and ignoring the chair's groans under his weight. "Go ahead and have a piece, Harry!" said Hagrid, picking up some fallen icing with his finger and eating it. Harry thought to himself that it did look rather good, and this man was talking of Hogwarts whatever that was. He might as well eat some cake and find out. Cutting a piece, he sat in a chair across the table from the man, eying him as he pulled odd trinkets out of his innumerable pockets. Finally finding a piece of crumpled paper, he smoothed it out in front of Harry.
"Ah, here it is. Knew I shoulda put in my coat pocket," said Hagrid, adjusting his pants. Harry looked at the paper, wary of its previous home. Read its small print, he got from it that he was a wizard and this was his acceptance letter to wizarding school-Hogwarts they called it. Looking up at Hagrid, he saw a flash of movement before Hagrid seemed to try to act natural, failing miserably at that. The tip of his finger looked a tad green which made Harry wonder what he could have been doing before he looked. Harry was starting to warm up to him already.
"So tha' is yer letter. Figured I'd take ya shoppin', too. The muggles shouldn' be back soon."
"Hold on, Hagrid. What is this Hogwarts, anyway? And how could I be a wizard? They're just in fairytales," said Harry, starting to feel like this was an elaborate practical joke to get him in trouble.
"Come on, Harry. You ruddy well know yer a wizard. The whole wizarding world is obsessed with ya! Come on, I'll take ya to Diagon Alley and show ya. You're famous! And while we're there, we can get yer school supplies, too," said Hagrid, seeming to skip parts of the conversation dealing with explanation. Thoroughly confused, and quite frankly curious, Harry looked at him, gauging his sincerity. He looked like the most trustworthy person he'd ever seen. Placing his doubts behind, he responded, "All right, Hagrid. I'll go with you but only if you explain to me about all this magic stuff on the way."
Hagrid looked at him bemusedly. "I suppose I might as well play along to this gag." Hagrid must have thought he was pulling his leg. That changed before they stepped out of the door, Harry having asked five questions already.
A/N: First chapter ever and it feels good. Tell me what you all think. I know it was short, but I'm just feeling the waters with this.
