At least it is if any of the following is true:
- I owe you work of any kind: fiction, non-fiction, feedback on a story, interview responses, whatever. If I committed to do something for you and have not gotten it back to you.
- I have not returned your email of whatever sort.
- I am supposed to attend your con and have not signed up for programming.
- You were on the train trip and I have not added you as a friend yet.
- You thought I was going to post about something but I haven't. (Except for Cleveland and Chicago shows, I know, I'm on it.)
- You are waiting on me for anything.
