Enjoy! Disclaimer- I own my cup of tea I'm drinking. That sentences purpose was mainly to distract you from the fact that I don't own Sherlock.
Johns alarm clock went off, as usual, at seven-thirty AM. He rolled out of bed, got himself dressed for the day, brushed his teeth, and entered the sitting room of the flat. He walked into the kitchen, about to make himself his customary toast with jam, when he saw Sherlock, already in the room, completely immersed in his experiments.
"...What?"
Sherlock turned to face his flatmate.
" John, yes, there's tea on the table." He motioned towards said table, which was covered in test-tubes and beakers. " Try not to confuse it with the Nitric acid. Should be milk somewhere around there as well. Try to avoid confusing that with the hydrated Sodium Hydroxide solution." Warned Sherlock. John stared mutely.
" You made me tea?" He eventually asked.
" It would appear so, John."
"...Why?"
"Why not?" Sherlock looked back up at John. " It's right there."
John grabbed the tea filled cup and sniffed its contents cautiously.
" What's that for?" Asked Sherlock.
"...This isn't some type of trick?" John inquired. Sherlock raised an eyebrow.
" No..."
" It isn't part of an experiment?"
Beat.
" No."
"...Alright then...Thank you, I suppose."
Sherlock nodded stiffly and watched carefully as John sipped at the tea. Truth be told, John had to admit that the tea was quite good. Very good in fact. Tea shouldn't taste like this...
" So, how is it?" Sherlock asked casually. John set the cup down and pinched the bridge of his nose.
" Sherlock, what've you put in my tea?" He demanded to know. Sherlock reddened a bit, embarrassed at being caught.
" It's nothing, John, really-" He started to assure, but was cut off by the Doctor.
" Sherlock. Tea. What's in it? Now would be good."
Sherlock sighed.
" Carboxymethylcellulose."
John stared blankly.
" Say that again?"
" Carboxymethylcellulose, John. It's deprived from wood. Non-toxic, it's perfectly fine for you to drink. I jut wanted to see what would happen." The Detective explained.
"...So it is an experiment." John said.
" Well...Yes. I suppose it's an experiment." Sherlock admitted. John glared at his friend, and Sherlock looked somewhat shame-faced. After a while John picked up his tea again.
" For your information, this Carboxymethylcellulose thing, it makes a good cup of tea."
Sherlock smiled thinly.
" Am I forgiven?"
John shook his head.
" Nope. Not forgiven...But feel free to continue putting this into my tea."
" That would imply that I intend to continue making your morning tea." Sherlock noted.
" Yes it would." John agreed.
Silence.
"...Well played."
And from that morning on, Sherlock made John his tea every morning, and every morning, he added a touch of Carboxymethylcellulose.
Never actually put Carboxymethylcellulose in my tea. Might later. I'll get back to you on how it taste if I'm ever able to obtain it. Please review, reviews are slightly below Sherlock on my list of awesome things. So they're pretty high up there. Go ahead. Make my day. Even if you don't, thanks for checking out the story, have a fantastic day, and DFTBA!
