Don't be silly, I don't own Sherlock!
Just something that popped into my head and wouldn't go away. I know it's silly, but I think it's cute (:
John walked up the stairs to his and Sherlock's flat and as soon as he opened the door his ears filled with Carly Rae Jepson's Call Me Maybe.
Suddenly Sherlock slid into the room, in only a pair of black boxers, holding a graduated cylinder up to his face as he belted out the words into his makeshift microphone and spun around the room, wet hair dripping and long limbs moving erratically, unaware of John's presence.
John smiled widely, never having seen Sherlock this carefree. He was glad he'd gotten home from work early.
