The Letter

Heyyy! So this is based off a reddit writing prompt I saw soooo ya xD

On everyone's 18th birthday they receive a letter. A letter from their future selves. Some people receive long letters about their future jobs, future lovers or messages about decisions that will define your future. But when Sherlock Holmes received his letter that had only an address and a note underneath that said "NEVER VISIT". Well..I think you can guess what happens next.

"You'd think my future self would know me better." Sherlock said to himself as he got into his car, typing the first set of coordinates into his GPS.

The currently unpopular "consulting detective" drove for a solid hour before he arrived at the address his future self wrote to him. It wasn't at all what he thought it would be.

You see, Sherlock thought the address would lead him to a crime scene, or an abandoned building, or even a drug den. But in front of Sherlock stood a house. It wasn't a big house. It was in the middle of the countryside. It was white and one side of the house was covered in Ivy. It was kind of mundane. Sherlock was beginning to wonder why he didn't want him to come here.

He got out of his car and knocked on the wooden door. He waited a few seconds before he heard a voice shout "Just a minute!"
Judging from the voice they were around sherlocks age, male, probably around 5'7.

The boy opened the door. Sherlock was taken back. He. Was. Amazing. He had platinum blond hair, piercing hazel eyes, he was actually 5'8, significantly shorter than Sherlock who was 6'2. He turned 18 last week judging by the letter pinned up on the wall, he lived by himself too.

"Oh.my.god." The boy said staring at Sherlock. This made Sherlock tune back in and introduce himself.

"Um hello...I'm Sherlock Holmes"

"Sherlock Holmes.." the boy said in unison.

Sherlocks face was suddenly riddled with confusion. How did he know who he was? Who is he?

The boy picked up on this and introduced himself, "oh sorry!" He said flustered.
"My names John. John Watson." He put out his hand.

Sherlock shook it as the boy-...John, welcomed him inside. "My future self told me all about you in my letter. I turned 18 a week ago by the way." John explained.

He took his letter from off the wall and handed it to Sherlock. "Your future self wrote something too, I didn't read it because I thought you should see it first."

Both the boys sat down as Sherlock read the letter out loud:

(Future Johns paragraph)

Dear John Watson (aka past me),
I'm writing to you 5 years into the future and gods I have a lot to tell you. But I'll keep it simple.
A week after you receive this letter, a man will show up at your doorstep. His name is Sherlock Holmes. You will go on fantastic adventures with him, you'll solve crimes, he may fake his death once or twice but you'll slowly care about him more and more. He needs us and we need him.
Good luck little me :)

(Sherlocks paragraph)

Hello there younger me,
Yes. I did steal Johns letter without his knowledge and added my own note.
I know that my note was...confusing to say the least. But the reason why I put "never visit" next to Johns address is because I knew if I put "visit" it wouldn't be as exiting so you'd probably not go. I do have something else to say though. In exactly 2 years you and yjohn will- crap, Johns coming, I have to go. Goodbye consulting detective.

Consulting Detective? Sherlock thought to himself. Brilliant!

"Sooooo...." John began.

"So.. how do you feel about going to the park?" Sherlock said.

"Sure" John said with a smile, blushing slightly.

One year after meeting

Sherlock and John had become inseparable. They were best friends. They solved one case after the other. They even fell in love with each other. Dated until Sherlock in faked his own death for 3 months. (Yes I know it was 2 years shush.)

2 years after meeting

They solved their little issue and started dating again. They loved each other. Mycroft and Lestrade got together too surprisingly.

3 years after meeting

Sherlock proposed to John, and of course, he said yes. They had their wedding in the winter, on Christmas Eve. It was like a movie. Totally amazing.

4 years after meeting

John and Sherlock adopted a child, her name was Rosie. She learned how to talk at 5 months old. Somehow she inherited Sherlocks brains and Johns stamina within the short time they were together. Her first word was Sherlock, John was jealous of course but he soon got over it.

5 years after meeting

Lestrade arrived and handed the Baker Street boys a letter. "Here, it's time to write a letter to your past selves" then he left.

Sherlock picked up the paper and wrote an address. He kept it in his mind palace for 5 years for this day. He then wrote at the bottom "NEVER VISIT".

He then went and stole Johns letter to write his own little message.
