When Sherlock thinks, he need people to disappear. When I do, I just need to walk, - to walk without thinking where to go - just to walk.

Sherlock says bad things, overdoes things, do crazy things.

As people observed, he does not have any friends - well, true that is.

Timid, does not express feelings naturally, hence does not have normal emotional feelings - some may exceed, mostly lack of.

He seldom eats too - well, that is a different story.

Does things very randomly, yes.

Absurd.

Most likely, everything about him - more like me.
