It was early morning when Chris Griffin was doing the morning delivery, and when he crossed by Herbert's house, Herbert came out and asked if he wanted a popsicle, but then their was a scratching sound and he had to go back inside to see what it was. The owl bringing The Daily Prophet: International Edition had arrived, so he paid it and started reading it, and front page headlines said that Hogwart's school of Witchcraft and Wizardry's defense against the dark arts teacher just died, and so they needed a new one.
"Hey, Jesse." Herbert said, "Wanna go meet Harry Potter, the boy who lived?" Jesse was his old dog that could not walk on its hind legs. "Mmmm, he looks like a scrumtious boy, too." Come on Jesse, we're going to England. Herbert used a shrinking charm to make everything smaller to make it easier to apparate too, then he put up a FOR SALE sign on his yard. Then apparated to Hogsmeade, and got his first look at Hogwarts in a long time, he went to school here, it felt good to be back.
He got into the doors and was very surprised that Filch was still working here, even though he was just 10 years older then him. "Who are you." Filch demanded. "Argus, don't you recognize me?" Filch knew who it was just by how he pronounced his S. "What do you want Vertper?" He demanded. "I just want to take up the defense against the dark arts post and educate the good looking wizards(mmmmm) and witches." Very well, go see dumbledore."
When Herbert got to Dumbledore's office, he told him he wanted to get the post. And so he did.
