When any movie or television show you watch, any song you hear, anything weird thing your family does is automatically examined for plot bunny potential. When you rush home from a wonderful day at the lake to be home when the SFFA awards start. (GUILTY) When you keep a list of names to use for OC's so that if inspiration doesn't strike when you need it to you have a back up. Getting your child involved in fanfiction and then speaking in secret code with them, much to the annoyance of their siblings. When you begin naming pets not only after Canon characters but after OC's you've either written or admired. I swear I'm going to name the next animal we get "SHAI" after obi_ew's OC!
