All dialogue. Enjoy!

"Sherlock, why the hell are you pouring milk down the sink?"

"Bored."

"Pardon?"

"Bored. I am conducting an experiment to see whether milk goes down the sink faster or slower than other fluid, in this case water."

"And you did all of this because you were bored?"

"Yes."

"Bloody hell, Sherlock! I just bought that milk yesterday, and you're just pouring it down the sink. Now I'll have to buy more. Milk costs money, and money doesn't grow on trees!"

"Well, technically money is made of paper and..."

"Oh, shut it! You're well aware that it's not, you just assume I'm stupid enough to think so. You are going to buy more milk later."

"Dull."

"Well, you see, Sherlock, sometimes life is dull, get over it."

"What if I refuse?"

"Then I'll hide your cigarettes."

"You already did that, but of course I've already deduced where they are."

"I'll stop bringing you tea."

"I can live without it."

"Ok? The how 'bout this? I take all my stuff up to my old bedroom, so that you'll be in your bed cold and alone, without anyone to wake up to the next morning. And you can forget about the sex as well. In fact, you can forget about kissing too. You are never getting close to this body again."

"Please, like you would do that..."

"Oh, I would. I'll just get my stuff then..."

"No, wait! I'll get the milk!"

"I thought you said it was dull."

"Waking up without you is duller."

You can expect many more of these, whether you liked it or not ;)
