Hey guys! Short little story, prompt from the wonderful Kristy LeeKL!

"Alright, Sherlock, I'm leaving," John informed his friend.

"And Mrs. Hudson left as well,?" Sherlock replied, stretched out on the couch.

"Yes. I'll be back soon, look out for any good cases," John called, thumping down the stairs.

As soon as he left, Sherlock rolled over on the couch, failing to find any interesting cases. His eye caught a package Mrs. Hudson had given him, saying Mycroft had it delivered. He got up and pulled the box over to him and ripped off the tape. His eyes widened when he saw the contents; old relics of his childhood.

A faded, slightly bent pirate hat, and a wooden sword.

He ran his hand over the sword lovingly.

"Come on, Redbeard!" a young Sherlock called, splashing his boots in the water.

Redbeard, or better known as his best friend Victor Trevor, followed closely behind.

"We have to get to the treasure first!" he replied, waving his sword.

Sherlock smiled ruefully.

Carefully, he picked up the pirate hat and placed it on his head. It had once been too big for him, falling over his eyes and obscuring his vision; but now it was comically small on him.

He lifted the sword from the box, and cautiously waved it in the air.

And suddenly, Sherlock was a child again, playing pirates.

His mind palace spun a new story for him, one of missing treasure.

Sherlock swung the sword, fighting off any foes, putting all his criminal fighting skills to the test.

"Come on, Redbeard. One last time," he muttered.

John scribbled a prescription onto a piece of paper and handed it to his patient.

"Try that for a week, once a day, if it doesn't seem to help, come back and see me," he said, for what had to be the tenth time that day.

His patient thanked him and left.

John ran a hand through his hair, relieved that work was over for the day.

He hailed a taxi, and got in.

When he arrived back at 221b, he opened the door slowly to see Sherlock playing pirates, lost in his own world.

John recorded him quietly, and then, as an afterthought, sent it to Lestrade.
