John
Sherlock and I moved into the flat together two days after our initial meeting. One of the first things I discovered about Sherlock was that he was a very messy person. His mind was so organised but that came at a cost. He had no respect for his body or the flat we shared. He rarely remembered to eat or dress and he became bored very easily. When he had finished with something he would chuck it onto the every growing pile of discarded items strewn all over the floor of 221b Baker Street.
Another thing I learnt was that he was a complete genius but that he had no idea how to interact with other human beings, expecting us to understand how his mind worked and being perplexed when he realised we didn't. As the weeks went on I was completely drawn into Sherlock's world. A world of danger, mystery, excitement and surprises; an unpredictable world of frustration and confusion and hard work. A brilliant world of genius. I found myself needing to sleep and not minding, having no nightmares and wanting to wake up in the morning to learn more from the world's first consulting detective. I found myself enjoying life. In three months I no longer had any of the symptoms I had first been to the therapist about and she told me I had no more need of her. The only therapist I need was Sherlock Holmes. He had picked up the broken pieces of me and put me back together again, improved.

Early on in our flat-sharing I decided to include John in my consulting detective work because I felt an amiability towards him. He didn't understand me, obviously, nobody does but I understood him. I don't mean that I could tell what he's been doing every day when he came into the flat, who he's been with and what he's eaten which is how I understand the rest of the world. I mean I could tell how he was feeling, when he was tired, when he was frightened. He was frightened a lot in the early days. Luckily I was on a case so I wasn't bored enough to shoot holes in the walls- John jumped out of his skin when Mrs Hudson took out the bins. As time went on John learnt about my methods. He went from completely clueless to vaguely competent at observing evidence and drawing conclusions from those observations although I'm still a long way from letting him loose on his own with any significant level of confidence in his abilities.
The Earth revolves around the Sun, apparently. John found it astounding that I didn't know that even though I'm a genius. I only remember things which are useful to me and my job as the world's first consulting detective, although I only take the interesting cases.
The one thing that does annoy me about John, however, is the fact that he's a doctor and consequently so bloody health conscious. He threw away my emergency supply of cocaine and if he caught me wearing more than one nicotine patch he would rip off the patches until I was only wearing one. He ranted at me for thirteen minutes when he realised I hadn't eaten for a week when I was trying to solve a case. Now he watches me eat at least one meal a day and I do find myself feeling more energetic. John also reminds me to change out of my dressing gown before I visit crime scenes, which is always helpful.
