Oh, Sherlock... [John pinches the bridge of his nose before wiping a few stray tears from his eye.] Have you got a pen? Anything to write with? I want you to write on your hand or anywhere that you'll see it easily--paint it on the edge of your bloody tablet if you have to:

'Read the full conversation before replying.'

You're gonna be flipping out for the next however long this lasts if you don't.
