You and Sherlock were flatmates/co-workers, Sherlock sat at his desk in the living room, typing away on his computer while looking over a few pages of a book that sat next to his computer. You walked into the room, glancing at what Sherlock was doing but you didn't bother questioning or anything of that sort, you shrugged it off as you walked to the kitchen to grab a snack, then again, it was a long day of cases and mystery and you two just got home.
