Everything Has Its Place

"Mycroft has OCD, he doesn't even know he's doing it" Sherlock says about Mycrofts inability to even let the door hanger be astray at 221B. Whenever Sherlock wants revenge on Mycroft, he puts things just out of place enough so that his brother is the only one to notice. Lestrade is getting a bit fed up when it's on their anniversary. Rated M for potential future chapters.
