Writer's Block: Spilling Secrets

What secret (your or someone else's) do you wish you'd done a better job of keeping? View other answers

...I'm sorry, I have to ask: does Livejournal think I'm stupid? I'm not as careful as filthspigot about separating my LJ and personal lives, but what made them think that this question even made sense?

Let me break it down.

1. I have a secret.
2. I spill it, wholly or partially - a matter which is a source of personal guilt.
3. ???
4. I tell the entire world.

I mean, pardon me, but even I am not that lousy a prevaricator.
