AN: This will be a collection of Head Canons that I saw posted on the Facebook page, "So after that obvious and disgusting bit of cheating" -Lee Jordan. They were copied onto that page from .com/ However, I got them from the Facebook page. The head canons are accepted facts, although not confirmed by J.K. Rowling. I saw them listed as facts, so I chose to write stories about the best of them. I hope you enjoy and please review.
HC: Peeves attended Fred Weasley's funeral and was perfectly well behaved. (Although he did set off some dung bombs at the reception.)
Peeves the Mourner
All sorts of people showed up for the funeral of Fred Weasley. Family, everyone from Charlie in Romania, to his Great Auntie Muriel; friends, employees, and even people who just knew him in passing, like customers of his shop and students at Hogwarts. But there was one guest that no one expected to see.
When Peeves the Poltergeist showed up to the funeral, everyone held their breath, waiting for the commotion. But the mischievous little man didn't do anything. He calmly floated down the line into the funeral home, wearing a somber black suit, as opposed to his usual bright jester's outfit, and took a seat, floating a foot above the cushion to be head level with everyone else.
When the service started, everyone watched Peeves with apprehension, but he sat quietly and respectfully, listening to the service. He didn't blow his nose in a theatrically loud manner, nor did he blow rasberries during the eulogy. He just sat there, quiet and respectful. No one knew what to do and everyone was silently waiting for the mischief, right until Fred was lowered into the ground.
At the reception, Peeves was slightly forgotten, the Weasleys grief took everyone's attention. And while the hugs and tears went on, Peeves just floated silently in the back. And of course, he eventually set off some dung bombs near the butterbeer and swooped away, but no one really minded much. Some people who attended swear they saw George Weasley give the dung bombs to Peeves himself. And Peeves still haunts Hogwarts to this day, wearing his traditional jester outfit, with one small "F" stitched on the right breast pocket, a silent tribute to one of the only pranksters to ever earn his respect.
