"Well, I'm off to tennis. See you in a couple of hours."
"Okay, I'll..."
"...What?"
"...What are you wearing?"
"My tennis gear! All the best tennis players dress like this."
"You're not Andy bloody Murray, Sherlock! Where did you get all that?"
"Town."
"Town. That's a little vague."
"Yes."
"...Not going to give me anything else, are you?"
"No. Laters!"
"Sherlock!"
"What, John? I have to go, the lesson's starting in ten minutes!"
"Money?"
"John, are we seriously doing this now?"
"Sherlock."
"Fine, I have money. I have a phone; my phone. I will try not to die. Alright?"
"...Satisfactory."
