Now and then I think of when we were together
Like when you said you felt so bored that you could die
I told myself it was a lovely phase
The lack of murders and the peaceful days
But now I almost wish there'd be a serial killer...

You can get addicted to a certain kind of madness,
Like sociopathic fascination with the end.
I guess you never really seemed to care,
and that was something that I could not share.
But I always helped you through, and now it's over.

But you didn't have to take the Fall -
tell me nothing and then hang up like I wasn't watching
I'm trying not to let it show,
but when you hit the ground it was my heart that broke.

No, you didn't have to lose it all,
Leave me all alone with nothing but the life you made me.
I guess I have to feel this, though -
Now you're just a body that I used to know.

Sherlock (forgive my rather [bad word] accent):
Now and then I consider all the variables involved in my possible return, and [bad word] to my attention that the subtlety required would be far too much to ask of either of us, when emotions are involved. Obviously. Inevitably, [bad word] to the conclusion that in order for my plans to [bad word] to [bad word]  this charade shall have to continue considerably longer than I'd originally planned. It is unfortunate, and occasionally irritating,
But I'll just have to live this way,
shielded by the cover of a grave.
I'd bet that you could let it go,
But I have to act deceased, just like a body that you used to know.
