Secret!

Carry a secret to one's grave -- it's honorable if it happens. Secrets are sacred and yet important that's why it is being kept. It is something that would really matter. It could be a catalyst that can start a reaction, a pseudo idea in order to make a mislead, a scar that occurred in the past, or a plot which is about to unfold. These are just few conceptions of why it is being concealed as confidential.

Though the very essence of telling it to a confidant makes it not a secret anymore. It is being revealed in a very sense and literal manner. It was told, and it could be told - that's the premise and it has the same chance of being unveil.. No guarantee, come worse, it could boomerang as a blackmail.

Telling a secret is like playing with fire.. So better not get close to it!
