"Sir," said Harry, still grinning, "You don't know how good it is to see you." Pulling open the door wider, he said, "Please come in. Would you like some tea? Or brandy?" Dumbledore stepped inside, and Harry shut the door behind him.
"Tea would be lovely Harry," he said, looking bemusedly at the eager young boy in front of him. "It's been a long journey."
Before Harry could move, Vernon and Petunia Dursley emerged from the sitting room, griping about the late hour and the nerve of some people. They stopped dead when they saw this tall figure, so obviously a wizard, who radiated power and practically screamed, NOT NORMAL!
Stepping up behind his professor, he whispered into his ear, "Please sir, don't be too hard on them. Petunia was jealous, and Vernon was scared."
Giving Dumbledore space to think about that for a moment, he looked at the 'family' he'd had for the past six years, and, trying to defuse some of the tension, said, "Uncle Vernon, Aunt Petunia, I know you don't like anything to do with magic, but as soon as we are finished here, we'll both be gone, and you won't have to see either of us until next year, so please just don't freak out. This is the headmaster of my school, Professor Albus Dumbledore, and he is here to pick me up. Before he can do so, I daresay there are some things we will need to talk about."
Everyone stood in stunned silence for a moment at this little speech, until Dumbledore snapped out of it and said, "Quite right, my boy, now shall we proceed to the sitting room?" They did so, Harry dragging his Aunt and Uncle behind him, and settled on the chairs in there. Harry pushed his family down onto the couch, where they sat silently, glaring at Dumbledore and staring at Harry.
Before they could begin, Dudley tromped down the stairs, calling, "Mum! Who was at the door?" He stopped when he caught sight of the sitting room and the robust wizard dominating the scene.
Once again the voice of reason, Harry proclaimed, "Dudley! It's good to see you. This is my headmaster from school, Albus Dumbledore, and he needs to speak with us about a few things. Come in! Sit down! I promise he won't hurt you." Slowly coaxing his cousin into the room, Harry guided Dudley to the couch and sat him between his parents. Seating himself once again, he looked expectantly towards Dumbledore who was giving him a calculating look.
Taking the cue, Dumbledore began, "Well! Firstly, I must say how pleasant it is to see you all again. The first order of business we must cover before we leave is concerning Sirius' will. He left you everything he owned, along with Grimmauld Place. The Order has, for a time, vacated the building, as we are not sure of the true ownership. We fear the house may have automatically passed into the possession of the next black in line, who would be Bellatrix Lestrange, his cousin."
While Dumbledore paused to give him a moment to absorb this, Harry said, "I can assure you, Headmaster, that Grimmauld Place is firmly in my possession. Sirius went through all of the proper channels to make sure of that. If you wish to make sure, you may call Kreacher to us, and I will ask him." While Dumbledore gave him a wide eyed stare of incomprehension, Harry's relatives, who had been thus far quiet, decided to speak up.
"Your godfather's dead? That Sirius Black?" said Uncle Vernon, staring greedily at Harry. "And he left you a house?"
Harry smirked and said, "Oh, why yes. He was murdered this past school year in the basement of our government headquarters by a madwoman during an epic battle. Didn't you know we were in a war?"
