A/N Yeah, I've been watching Friends and my sister-in-law has the same 'thing' as John. As always I hope you enjoy and as always I OWN NOTHING.

John strolled into 221b with his hands fulls of bags. He cast a quick glance over the living room and saw that his flatmate was sat in his usual chair reading.

"Oh good, you're here," John began as he bustled around in the kitchen, "Sherlock, I picked up a chinese on the way home."

"Not eating, John," came a distracted reply.

"Don't start. I'm putting some out for you any...hang on, whats the time... Sherlock flick the TV on will you; Tinker Tailor Soldier Spy is on."

"What channel?"

"Erm...I think it's channel 4," John said as he stepped just inside the living room so he could see the screen. Sherlock flicked onto channel 4, "Thats it, thanks."

Sherlock then began adjusting the volume; he settled on a number and then dropped the remote. John couldn't help the small 'urgh' that escaped his lips.

"What?" Sherlock shot him a look.

John grimaced, "Nothing. It's just...well, can you set the volume to an even number please."

Sherlock quirked his eyebrow, "An even number?"

"Yeah," John said as he crossed the room and picked up the remote; he adjust the volume himself from a nineteen to a twenty, "It just irks me when it's on an odd number."

Sherlock blinked and tilted his head slightly, "It irks you?"

"Yeah, I know," John looked at him and shrugged, "but it's just one of those things."

"One of what things?"

John chuckled slightly, "Sherlock, don't even try and deduce this; it's just a thing." John turned back towards the kitchen.

"John," Sherlock started, "You don't make sense sometimes."

John stopped walking and smiled, "Sherlock, you don't make sense most of the time."

"I don't have 'things'" Sherlock protested.

John snorted, "You have a sock index."

"Thats practical."

"You keep body parts in the fridge."

"Experiments."

"You shoot holes in the walls."

"Bored. Look, John, I think you'll find that I don't have a 'thing'."

John coughed, "I wouldn't go around telling people that, Sherlock."

"What? Oh, grow up, John," Sherlock rolled his eyes.

John gathered plates in his arms, returned to the living room and sat down. He passed a plate to a reluctant Sherlock.

"It isn't the enemy," John said as he passed over a knife and fork, "You aren't even on a case."

Sherlock stared for a moment at the utencils in his hand, "Why aren't we using chopsticks?"

"Oh, cos this is just easier," John replied as he settled down.

"But it's Chinese."

"Just eat."

"Not without chopsticks."

"Sherlock..."

"You should eat Chinese food with chopsticks."

"Look, what does it matter?" John asked getting annoyed.

At that Sherlock reached for the remote and turned the volume up one number, "What does this matter?"

John glared at his friend but then they both caught something in each others eyes and burst out laughing.

"Ok, ok," John said as he calmed his chuckles, "I'll get chopsticks, you change that number and then can we please try and watch this film."

"John," Sherlock began as he did as was told and turned to volume back to an irk-free even number, "It really would irk me if I had to eat this food with a knife and a fork."

"I'm getting you the chopsticks now. Just hang on."

"No, John, I don't understand."

"Understand what?"

"It's irrational. How have I never noticed before?"

John handed over the chopsticks and chuckled at the half puzzled/half disgusted with himself look on Sherlocks face, "You're human, Sherlock. Get over it."

Sherlock glowered at his friend, "Get. Over. It?"

"Yeah," John felt no threat. He sank back down into his chair, "Sherlock Holmes, you have a 'thing'."

After a moment of their eyes being locked on to each other, they burst into laughter once more.
