Honestly, I don’t agree with all of the points. I try to avoid writing about people I know, though occasionally, they do inspire me. And I have never at a party riffled through other people’s things, personally, I think that’s just an invasion of privacy.
But the others, I felt were head on.
Especially number 10. I have in the past dated people and been friends with people who didn’t understand how crushing a rejection letter can be. When you are already reeling from a rejection that logically you know shouldn’t be personal, but emotionally is, the worst thing you need is someone telling you to suck it up and that it isn’t a big deal.
I would add:
11) Don’t ask the writer how much money they have made off the work or when they are going to get a publisher.
What would you add?
