A/N: This story takes place in the same universe as "The Evolution of Fear", although you don't need to have read that story to understand this one. Chapters are sequential and will be 221 words or less. As always, I don't own these characters, Moffat/Gatiss and Arthur Conan Doyle do. Thank you to Insert Kick Awesome Here for suggesting this series!
Four-year-old Sherlock is playing pirate in his tree house. Normally, Mycroft is there with him, but today Mycroft is studying. (I don't know why he does all that schoolwork. It's so boring!) He decides to try something Mycroft never lets him do: swing on the vine to the other tree. The pirates in Peter Pan did it, and they looked like they were having a lot of fun!
As he gets ready to swing, a grownup voice yells from below. "Sherlock Holmes! Get down from there at once!"
(Oh no! Nanny!)
"You know those vines are dangerous, young man! Now get inside before you break your neck!"
Sherlock's greatest fear is that he'll never get to have any fun.
