You should do a short teen!lock fic! It's Halloween, and John is dressed up as the monster in Frankenstein. Sherlock, however, thinks trick-or-treating and dressing up are ridiculous and a waste of time(but secretly he has always wanted to, by mycroft never had time to get him dressed up cause he was busy) so John "convinces" (Pins down da fool and dresses him up) to go trick-or-treating dressed up as Doctor Frankenstein!
Boom here it is.
"Sherlock, come- we have one last year of a reasonable age to go out trick-or-treating, let’s go." John wasn’t necessarily demanding, nor did he seem truly in it. And, with a typical green face and tattered ware of Frankenstein he was an odd sight. Sherlock simply glanced up at him.
"In which greedy children go about in badly made outfits, and all the parents regret it. How about no, I’ve better things to do. John. I need not waste my time with candy." John smiled, he quite frankly wanted to go with his best friend, and we all know 16 year old boys are quite the little devils.
"Sherlock…. oh, but I got you a costume." Sherlock frowned.
"John, obviously I knew that." John in that moment walked simply to the bag, then he made a B line towards Sherlock who was just about to get up. The two teens ended up in a game of chase, of which both weren’t exactly slow, but- through the gift of luck. John cornered Sherlock, the costume bag on his hand and pounced on his friend.
"Now, you WILL be going out with me." Stated a proud John, Sherlock simply admitted defeat to his buddy and allowed himself to be partially dressed, wig, suit and all. At this time it was roughly 7 and the two boys went out. Mycroft, glancing uneasily at his dressed brother in passing to the loo.
"Trick-or-treat!" Chimed the boys as they went to each house. Gaining more and more candy.
The night was going along quite smooth, and they headed back. Sherlock looked shyly at John.
"John…. I’ve always wanted to Trick-Or-Treat." This time, it was John who knew, as his response went.
"I know Sherlock."
