That reminds me of a saying I once stumbled across. I can't for the life of me remember where it was, but it went something like this:
"The best stories have a hole in the middle of them."
It seems like leaving something incomplete invites people to step in and complete it themselves. It's a good way to craft something, and takes a lot of discipline to pull off if you're naturally inclined to take both sides, so if that's your pattern I certainly applaud you for doing it well.
Also though I imagine you have to suffer quite a bit of abuse from people who don't see what you're doing. Kudos to you for handling it well - I saw your response in this story to one person who was condescending and you were very poised.
