Author's note: This story takes place during the Trio's fifth year. It doesn't exactly follow the fifth book exactly and I've used some characters I created from another HP story I wrote, so if you don't recognize any names, that's why.
Harry Potter was in a very foul mood. Quidditch practices weren't going so well, his hand still stung from Umbridge's detentions, Cho Chang was acting weird around him, Hermione kept nagging him and Ron about studying for their O.W.L.s, Snape was being a royal pain as usual, and Hagrid still hadn't come back from wherever he was. The only thing that brightened him up were the D.A. meetings and Dumbledore had an important announcement as all the students ate in the Great Hall that night.
"I have an important announcement," Dumbledore said as he arose at the head table, lifting up his hands. "For the next two weeks, Hogwarts will be home to American Muggle students from Stoneybrook, Connecticut who will be visiting us in a special exchange program. However, I don't think it's been made clear to them that we are an actual school of witchcraft and wizardry. They seem to be under the impression that we are Muggles pretending to be magic folk and Hogwarts is a theme park."
There were indignant sounds all around, the loudest coming from the Slytherin table.
"I want everyone-" he gave a hard look at the Slytherins as he said this, "to treat our guests with the respect they deserve. Ah, and here they come now," he said as the double doors opened.
