Alright, well. Here is the beginning of a little compilation of texting between various characters (primarily Sherlock and John).
This is a collection of texts RPs between myself and msmeow (my beautiful and wonderful John~)

And now, I give you The Texting Archives of 221B!

Sleep is such a waste of time! -SH

Some of us have work in the morning. –JW

Oh, don't be ridiculous, John. You won't be doing anything. -SH

I have patients, Sherlock. I treat people. –JW

Pathetically over worrying parents and hypochondriacs do not count as patients, John. –SH

And the last time I checked you didn't have a psychology degree. So, you shouldn't be treating the hypochondriacs anyway. -SH

Rude. –JW

No, John. Just blunt. -SH

Every doctor gets his or her share of hypochondriacs. And I do have patients with legitimate problems. –JW

Right. And all of my clients are mentally stimulating. -SH

Forget it. I'm bored. Stop pretending to sleep. I need to find something to amuse myself with. -SH

Come to my bed then. –JW

Why? Your room is incredibly dull. And if I do not want to sleep, why would changing beds do anything? -SH

Forget it. Where did you put my cigarettes? -SH

Because I'm betting I could make you tired enough to sleep for a while so I might be able to. –JW

I doubt it, John. I hardly sleep after cases as it is. What are you going to do? Talk me to death? Mycroft tried. And let's just say that didn't work out well for him, if I remember correctly. Which I do. - SH

Just tell me where you stashed my cigarettes, John. -SH

Think of something that I could provide that would increase serotonin levels and endorphins at a high rate that would then cause a rapid decline in cognitive function and exhaustion. –JW

I believe the term you're looking for is sex, John. And I thought you said you were tired. Not to mention, I do not see how that would work. Milk contains melatonin which causes drowsiness; little good that did me. -SH

I might be tired, but that doesn't mean I couldn't wear you down enough to get you to tuck it in for the night. –JW

John, I never knew you to be the type of man to give a half asserted performances. Besides, I'm not the typical blonde you picked up at a bar like... What was the last one? Mindy? Miranda? I am not ordinary. I doubt a simple physical exertion could make me sleep. -SH

It isn't half arsed just because I'm tired. Also, considering the fact that it's still novel it doesn't take as much to get you off. –JW

... -SH

Forget it. I found my stash. -SH

Dammit, Sherlock. –JW

Shh, John. I thought you wanted to sleep. And I certainly have enough to keep me busy through the night. Stop complaining. You're getting the sleep you wanted. -SH

You were doing really well. –JW

I'm disappointed. –JW

For god's sake. They're just drugs, John. I fail to see the big issue. Besides if you didn't want me to find them you should have hidden them properly, or gotten rid of them. You did neither, so I am not too concerned in your alleged 'disappointment.' - SH

Fine. Good night. Please don't set anything on fire before 600 when I have to get up. –JW

You mean go to "work." And I can't promise anything, though I am finding my bed rather too comfortable to move from at this given moment. -SH

No, I mean get up and get ready to go to work. –JW

Same difference. -SH

Good night, Sherlock. –JW

Hmn. -SH

Sleep well, John. -SH

I would say the same, but I know you probably wouldn't want to. –JW

I do not understand the point of it. So no, I really wouldn't want to. Unfortunately it does happen on occasion even if I do shoot up. Your sentiment is noted though, John. Thank you. –SH

Thanks for reading~!
