Sherlock fanfic.
And in the time of his absence, John has bought a cat.
And sometimes it ignores him.
Sometimes it goes out and doesn't come back for days.
One day it might be gone forever.
And sometimes it falls asleep in his lap, after an outing, like nothing ever happened.
And sometimes it looks at him like he is stupid.
And sometimes it purrs.
And sometimes it trots around his heels. Tripping him.
And sometimes it's so bloody annoying he wants to strangle it.
Like when it refuses to move from his chair.
Like when it meows for hours on end for no apparent reason. Bored.
Or when it steals his food when it thinks he isn't looking.
John has bought a cat.
So naturally he named it Sherlock.
