I have a terrible secret, I burned down a wooded park ten years ago.
Wow, I never would have guessed that. How did that happen?
It was an accident, I started a fire to cook and it got out of control. I didn't want to get in trouble, so I never told anyone I did it.
Burning down a wooded park is arson and is wrong since it causes property damage and the possibility of injuring others. If there was extensive property damage you may have to pay for that.
It's my secret and I'm not going to tell anyone, I don't want to get into trouble.
I know you don't want to get in trouble, but you have to confess to this. This secret is weighing you down and you'll never feel free until you admit to what you did.
