Like, one written spur of the moment, or a particular favorite? Pairings? Fandom?

Spur of the moment is always fun, but favorites are nice, too; I’m content to read other ships, but I have a deep love of John/Sherlock and Jim/Seb and while I’m happy for any fandom I’m into, Sherlock is my ultimate favorite.  That said – really, whatever you feel like, I’ll be happy for. ^_^
