Wilson had been trying for years to get House into the Christmas spirit. He had yet to succeed.
House hated everything about Christmas. The songs, the obligatory gift giving, he barely even tolerated Christmas cookies. And heaven forbid anyone call him out on it in a Christmas themed way, like calling him Mr. Scrooge or the Grinch. It really wasn't worth the resulting rant about commercialized Hallmark holidays.
So when he caught House playing a Christmas carol on the piano in the apartment, Wilson was understandably shocked.
"I thought you hated Christmas songs?"
House looked vaguely guilty. "This one doesn't count! I heard it on the Doctor Who soundtrack…"
Wilson squinted at him, "You're such a nerd."
House laughed, "As if you have any room to talk!" and went back to playing.
"Borrow or steal, I'll find a way to be with my Lover, upon Christmas day! And I'll run and I'll roam, I'll cover the ground, this Christmas I'll see you, I'll be around!" House didn't often sing but his low baritone was just as pleasant as Wilson remembered.
He smiled softly as House continued to play. A Christmas miracle.
A/N: The song mentioned is "The Stowaway" from the Doctor Who 3rd series soundtrack. And it is, in fact, the only Christmas song I've ever liked.
