This is mostly one shots, that are very loosely connected. The main theme is Sherlock's time in Serbia, and being back. There is also a song that is tied into a few (link in chapter 0).
This story is to be understood as a continuation of the oneshots "Pants", so you should have read it before. It's about how John struggles to teach Sherlock a little bit to understand the social interactions of his fellow men. And Sherlock struggles to learn. ...and in the process, sometimes taking unusual paths.
