Harriett couldn't take her eyes off the giant. Nobody seemed to want to explain things, so she decided to take it upon herself to get answers. "I'm sorry, but I really don't know who you are."
The giant wiped the back of his hand across his mouth, "Call me Hagrid. An' like I told yeh, I'm Keeper of keys at Hogwarts- yeh'll know all about Hogwarts of course."
Feeling very stupid, Harriett replied, "Er- no." Seeing the shocked look on Hagrid's face she apologized.
"Sorry," He turned to glare at the Dursleys, who shrank farther back into the shadows. "It's them as should be sorry! I knew yeh weren't gettin' yer letters, but I never thought yeh wouldn't even know abou' Hogwarts! Did yeh never wonder where yer parents learned it all?"
"All what?" Harriett was feeling more stupid every minute.
"ALL WHAT?" Hagrid roared. He jumped to his feet, his anger seeming to fill the whole shack. "Do you mean to tell me," He growled at the Dursleys, "that this girl- this girl!- knows nothin' abou'- about ANYTHING?" Harriett tried explaining about the things she knew about from school, but Hagrid waved her off, "About our world, I mean. Your world. My world. Yer parent's world."
"What world?"
The giant began yelling and a furious argument broke out, Uncle Vernon's courage kept wavering, but Hagrid's anger never once wavered.
Hagrid fixed Uncle Vernon with a furious glare and every syllable trembled with his rage, "You never told her? Never told her what was in the letter Dumbledore left for her? I was there! I saw Dumbledore leave it, Dursley! An' yeh've kept it from her all these years?"
"kept what from me?" Harriett asked expectantly.
"STOP! I FORBID YOU!" yelled Uncle Vernon, now in a panic.
"Ah, go boil yer heads, both of yeh." The argument continued would have continued, had Hagrid not turned around to face Harriett. She almost shrank back, but her curiosity got the better of her and she looked at him eagerly. "Harriett, you're a witch."
She looked back at the giant, her mouth opening and closing with no sound coming out. Finally she managed to choke out "A- a witch?"
"An' a thumpin' good one I'd wager." Suddenly Harriett was introduced to a new world, which the giant explained bits of. Her parents had been murdered and magic actually existed. She also got to read her letter, which read Hogwarts School of Witchcraft and Wizardry on the front in neat curly green ink.
When Harriett went to sleep a few hours later she was still thinking of all that she'd learned so far. She still couldn't believe any of it, even though it explained some of the more fantastical things that had happened in her life. The most recent was Dudley getting a light pink pig tail growing out of his bottom. She couldn't deny the existence of magic and was now feeling as if she actually had a chance to change her life now.
