Always so caring for Armys~
A mystery is also Sherlocks bedroom. Anything else in this flat is a little bit chaotic (or a big mess like in tld) except for his bedroom. It's always extremely tidy. I bet he makes his bed always after using it. And the fact that he was upset because John might be disorganized his socks index. And he has a strictly order in which he prefers his dressing gowns. Also he is in general a man who is very concerned about is personal appearance (and Johns). Sherlock Holmes is a huge fashionista.
