The Cataplectic Consulting Detective

It was always a mystery- to those who knew the man- why Sherlock was so... cold. Some (John, Lestrade, even Sherlock's mother) assumed that it was because of bullying. Others (Anderson, Donovan, and all the other people who disrespected him) believed that he did it just to get on others' nerves. However, there are two people who know the secret behind Sherlock's apathy-
Mycroft, and the man himself.
