Do you ever take fic commissions? There's a particular song that cries Johnlock to me whenever I hear it, and while I don't usually go for straight-up songfic, I can't help but imagine what you (you, in particular) would write if inspired by this one. So,

Hey! I’m really sorry, but I don’t! It has nothing to do with a lack of willingness on my part, but I’ve discovered the hard way that my muses just do not take kindly to direction. I’ve tried, believe! I blame my naturally contrary personality. Every single time I’ve tried to write to a particular request (unless the parameters were EXTREMELY broad), it’s like all of my inspiration dries up and dies. I’m so sorry!! I would if I could, honestly! 

I’ll answer this publicly, though - maybe someone else will be intrigued and contact you for the song details, if that’s all right with you? Writers - anyone’s fancy tickled by this?
