As a child Sherlock only had one friend, Richard, they became friend shortly after Sherlocks dad died. When everyone would tease him about being awkward, slightly closed off, and believing in time travel, Richard would defend him. "Psychopath" everyone would say, Sherlock didn't believe it "sociopath" was better but he was barely that he never hurt anyone, and still had emotion, just not as clear, but he would still cry, he wasn't completely emotionless. Most people thought he was because when he would meet them he would tell their life story without any regrets or emotions.
Then came high school. Sherlock had known they'd been growing apart for a few years, but one day in Junior year, Richard yelled, "Sociopath!" And threw him in the mud. As Sherlock wipes the mud of his face he wonders why for once can't he be normal.
Sherlock walked home that day feeling defeated. He wanted nothing more than to go to his room, play the violin and forget about the whole thing. But on his was up he saw Bill and James, Sherlock was always jealous of James he always had friends, his best being Miles, but his dad died recently and he was still grieving. Sherlock tries to play the violin, but his song is cut short, by the old memory of the doctor and the blue box, by now he knows that it was probably just a dream, but he holds on to the hope that one day he will escape his horrid, dull, mundane life and travel with the doctor.
