It was another boring day in 221B Baker Street. The curtains were closed and a tall and lanky consulting detective was rotting of boredom on the sofa. He looked to the side and saw the newspaper that Mrs. Hudson left on the coffee table. He reached for the paper and skimmed through the wonderful news of happy celebrations going on in London. "Boring," he mumbled. Why couldn't there be more murders and crimes on the papers? They never liked to go into detail on those articles.

A few pages into the paper, something caught Sherlock's eye. It was an ad. It wasn't very eye-catching, mind you. It took up half a page and was just a plain, black and white page with a soldier's picture. The ad read:

"Bring back pen pals! Write to a brave soldier stationed somewhere around the world!
General information:

- Your pen pal will be a member of the British Armed Forces that is stationed anywhere around the world.

- Visit www. .uk to receive a random post box number to send your mail to."

Sherlock sat up and reached for his laptop and entered the site's address. The site was the same as the ad. Plain. Boring. That didn't stop Sherlock from clicking the "Get your post box number" button though.

Once the page loaded, he was faced with a post box number. Despite his curiosity, he decided not to search where in the world that number could be. He stood up and looked around the flat for a blank piece of paper.

Hello, random soldier—

I would say man, but seeing as the number of females who have joined the service has increased over the years, I'd rather wait for a response if one does come than deduce with no information well I wouldn't say "no information" on who might be reading this letter. I would like to inform you that I find this to be neither exciting nor "fun." I was merely bored and found the opportunity… fascinating. Never know what one could learn from you. Oh look, bored already. I do hope someone responds quickly. I do hate the sluggish post system and would prefer to text. Seeing as that is costly in this situation. This would have to do.

– S. Holmes.

Sherlock folded the letter and placed it in an envelope. He scribbled the P.O. box number on the envelope and left it for Mrs. Hudson to find, and hopefully, add to her list of things to do. He was already bothered enough to write the letter. God forbid if he had to send it as well.

A/N: And there we go! Mostly inspired by the fact that I love giving (and receiving!) mail.
