Okay, this is something that I've been wondering about. Why doesn't Sherlock tell John about the fight he had in the apartment with the guy in the Arab like get up, when John gets home from the supermarket? And, then again in Soo Lin's apartment, when her brother ambushes him? Both times, John thinks Sherlock's kind of goofing off or not taking John seriously. Both instances are rather serious in regards to Sherlock's safety and yet he wouldn't share them, so I was just wondering what everyone's take on that is.
