Disclaimer: I do not own Potter
A week went by without any word from Hogwarts, and Petunia began to worry. What if they just had to go to Diagon Alley not knowing anything they needed to get? It wasn't in the Dursley way to go into something unprepared.
But, that night, as everyone was sitting down to dinner, there was a knock at the door. When Vernon opened it, an impossibly tall man with a scraggly beard and the longest hair he had ever seen on a man stood before him.
"Who are you? What Is your business here?" Vernon said shakily.
"Name's Rubeus Hagrid, I came from Hogwart's School of Witchcraft and Wizardry. Professor Dumbledore tol' me yeh needed some information abou' the school."
Petunia, having heard the conversation, walked up to the door.
"Oh, uh, hello Mr. Hagrid. Welcome, please come in." she said.
"Alrigh, so yer letter said to Dumbledore that yah had some things ter ask me."
"Oh, yes of course, well as you can probably guess we have never had any experience with the Wizarding world." said Petunia.
Hagrid knew she'd had a sister that went to Hogwarts, but didn't mention it, he could tell she either didn't want to bring it up or wasn't involved in her sister's life.
"Well, Harry and Dudley here'll need ter go ter Diagon Alley ter get their books and such. Oh, and between you and me, Harry has quite a fortune stowed away, yah know, inheritance from James an Lily."
Petunia flinched at the sound of her sister's name.
"Well, there won't be much use for that, Vernon and I are more than capable of paying for both of the boys' books and wand."
"Well alrigh then, but just in case, here's the key."
He handed her a small brass key.
"Go to Gringott's bank an say yeh need to make a withdrawal from Mister Potter's vault. Then help yerselves ter the gold."
Petunia thought it over. She didn't want to to use her sister and James' money, but she figured it's what Lily would have wanted, for Harry to benefit from her money
"Jus' go to the Leaky Cauldron fore' the boys have ter go ter school an tell the bartender yeh need ter get to Diagon Alley, he'll help yeh through."
"Okay, I uh, I think that's just about everything. Have you got any questions Vernon?"
Vernon merely grunted in response. He was still clearly not warming up to the idea of sending his only son to Wizarding school.
"Well then I suppose that's all, thank you for coming." Petunia said.
"No problem, hope ter see yeh again sometime." said Hagrid leaving.
The whole thing was surreal, but Petunia couldn't help but be excited to see the Wizarding world for the first time.
