Have you ever known a secret that you thought you should tell? Did you tell? If you've never experienced this, what do you think it would be like to know a secret that you think is dangerous?

I have known a secret that I should have told someone but I didn't because that would be mean because if i told their secret when they told me not to, they wouldn't trust me! I know that I probably would have told someone, but only if I knew they would not tell anyone else, and that they would not tell the person who's secret I told them, that I told them their secret. That could mess up so many relationships and friendships if people told everyone Else's secret and nobody would trust anybody!
