Possibly, I'm Insane

Sherlock had never really considered getting a tattoo before. It wasn’t that he had anything against them per se, just that he had never encountered anything he wanted permanently on his skin. He saw people covered in tattoos and wondered at how many things they wished unfailingly to see every single day. It seemed absurd to him. Sherlock, in those days, couldn’t imagine ever wanting to see anything every single day. Even a good murder would get boring.

But these days, looking at John and Oliver, Sherlock understands tattoos. There are things he wants to see every day, unfailingly, permanently.
