"Sherlock, goddammit, you promised!"
"John—"
"No. You promised me, no more experiments in my bedroom!"
"But I needed the necessary—"
"I don't care, Sherlock! Not about your experiments or whatever bloody scientific merits they may or may not present. This is my flat, too, and I'd like you to respect that for once!"
"…I'm sorry, John.
"Oh, you're sorry?"
"Yes, I am."
"Then why do you keep doing it?"
"Well—"
"No. Never mind. Just—just clean it up, alright?"
"Okay, John."
"Thank you."
"I'm sorry I upset you."
"I'm sorry I yelled."
"No, you're not."
"Well, you deserved it, a bit."
"I will be more cautious in the future."
"Right then."
"Where are you going?"
"For a walk."
"…When will you be back?"
"I don't know, Sherlock, why?"
"…No reason. I'm sorry, again."
"Why are you apologizing so much?"
"Because it's polite."
"Do you mean it?"
"Yes."
"Are you lying?"
"…Maybe a little."
"Jesus."
"But I will refrain from experimenting in your bedroom from now on."
"You're going to finish the bloody experiment while I'm gone, aren't you?"
"Not if you don't want."
"…Oh, just get on with it. How long do you need?"
"Another hour or two, at most."
"And for clean-up?"
"…Okay, possibly overnight."
"I swear—"
"Maybe you could stay at Sarah's."
"It's—"
"No, I remember, it's…Janine?"
"Abigail, Sherlock. And she broke it off a week ago."
"Oh, yes, of course. Well, there's always the couch."
"I'm still going for a walk."
"That might be for the best."
"Why, Sherlock?"
"I might need to clear the couch, as well."
"Bloody—"
"Science, John!"
"Yeah, bloody science."
"Thank you."
"Whatever, Sherlock, I'll be back later. Do not start another experiment until you finish cleaning up the others, am I clear?"
"Crystal, John."
"Damn right."
"…Now, where did I leave that foot?"
A/N: I got bored one day. A study in dialogue?
