John left this message stabbed to the mantle with the knife, wondering how long it would take for Sherlock to text him that this way of coding was stupid and childish. He knew Sherlock decoded his message in fifteen minutes the first time he left a note like this, this time it would likely cost him less time to read it than it took John to write it. Grinning John put on his jacket and left.
When Sherlock wandered into the living room half an hour later, he spotted the note on the mantle and smiled. John had left him a coded note again. These didn't take up much of his time, but it was amusing to decode stuff when there was no pressure and he could easily get a cup of coffee before he started without having to worry about the time he was taking. So that was exactly what he did: walked to the kitchen, made himself a cup of coffee, took the note from the mantle and plopped on the couch after setting his cup down on the coffee table.
Several hours later
John this code doesn't make sense at all, there is no logic in the combination of numbers and letters this way.- SH
John hears his phone buzz in his desk, and checked the message immediately because his next patient would arrive in five minutes. After reading the text he looked at his phone for a few seconds, shocked, before he started laughing.
And I was thinking you would see it in seconds, kids use this way of coding messages often. Don't complicate it too much and you'll see the solution. :) – JW
Sherlock grumbled at his phone when he read Johns answer and settled down to try again.
At five o'clock
'Sherlock some help please' John asked from the doorway. 'Busy' was the only reply he got. John huffed and hauled the groceries to the kitchen on his own.
'What are you doing?' John asked perplexed when he saw his note stuck on the wall with all kinds of coding mechanisms surrounding it. 'trying to decode your annoying note!' Sherlock shouted. John smiled 'Go sit down I'll make some tea and explain, alright?'. 'Fine' Sherlock walked to his chair and waited, pouting because he still didn't understand.
That evening Mrs. Hudson wondered why she could hear Sherlock shout angrily while John was laughing, hard. Most of the time they were both shouting or both laughing.
AN: anyone who can decode this him/herself can say that they are smarter than my version of Sherlock when it comes to the easy codes ;p
