"Up the stairs, boys! First door to the left, it's most likely unlocked." She said while following the delivery men that were carrying a small refrigerator.

The men opened the door and entered the small kitchen placing the brown box in the floor. "Where do you want us to set this up?"

"Just leave it there, I can handle it from here. Thank you!" She paid them for their effort and she turned around looking at the kitchen making a plan on how to rearrange the furniture so she could fit the new refrigerator. She didn't want to make too much of a change knowing that Sherlock won't like it, but a small change was needed. John deserved to have a fridge that would encompass just food when he opened it, not body parts.

(Y/n) finished setting everything up just in time for the two men that she considered to be her best friends. She could hear them arguing coming up the stairs.

"The only thing I'm saying is that you could have been nicer to her. After all she just lost her husband." John was saying his voice a little raised.

"My job was to find out who killed her husband not to offer her comfort, John. You can do that, you're good at that. If the roles would be switched the killer would still be out there, because you wouldn't have been able to catch him." Sherlock responded while entering the living room followed by an irked looking John.

"Stop fighting and come here!" (Y/n) called from the kitchen. She was sitting in a lotus position on top of the table a huge mug on her hands and a happy grin on her face.

Sherlock entered the kitchen and sighed when he saw the changes that she made. "There is a cup of tea on the counter for you!" she said before he could complain. Soon after John came too, looking at her perched on the table and slightly shaking his head. "Why do you always feel the need to sit on places that are not made for sitting?"

"I don't know, probably childhood trauma." (Y/n) answered and giggled then she continued "I got you something."

"A fridge." Sherlock said answering John's unasked question, while leaning on the counter and sipping his tea.

"Yes, for now on Sherlock can use the old fridge for his experiments and the new one will be for food. Only food." She added looking at Sherlock daring him to argue. But he didn't, he just threw a fake smile towards her and brought the cup back to his lips.

John came nearer to the middle of the kitchen looking at the new addition. "So this will be mine?" he asked pointing at the small refrigerator. (Y/N) shook her head vigorously her hair bouncing up and down.

John glanced at the old fridge then back to the new one, he turned towards (Y/n) and asked "Why is Sherlock's bigger than mine?"

(Y/n) new that she shouldn't say it, she knew that her jokes were sometimes not welcomed but she just couldn't stop herself from answering "Genetics!".

At first John just snapped his face back to her peeling his gaze away from his gift, then his face turned a dark shade of red and his throat had an involuntary reaction that sounded as a cough. Sherlock on the other hand was really coughing, he just took a moth full of tea when (Y/n) gave her answer, he knew her, he was used with her dirty mind, always finding something 'dirty' to joke about, but this time he was caught off guard.

(Y/n) jumped off from the table and went to Sherlock, patting him on the back until he was able to breath normally again.

When he calmed down, she realised that John disappeared and she smiled widely. "Oh, I'm on fire today! I'm pretty sure the waiter from Speedy's is still hyperventilating." (Y/n) turned back to Sherlock "Are you better?".

"Yes." He answered, his deep voice sounding even deeper.

"Good. I'm off. Tell John that the reason for him having a smaller fridge is that he won't be storing body parts in it."

(Y/n) took her jacket from the door handle and started putting it on while going down the stairs, leaving Sherlock starring at her descending form a small smile ghosting his lips.
