When you hear a true story, there is a part of you that responds to it regardless of art, regardless of evidence. Let it be the most obvious fabrication and you will still believe whatever truth is in it, because you can not deny truth no matter how shabbily it is dressed.
Sometimes when you get older - and I'm not talking about you, I'm talking generally, because everyone ages differently - things you think on and wish on start to seem real. And then you believe them, and before you know it they're a part of your history, and if someone challenges you on them and says they're not true - why, then you get offended.
What is true is already so. Owning up to it doesn't make it worse. Not being open about it doesn't make it go away. And because it's true, it is what is there to be interacted with. Anything untrue isn't there to be lived. People can stand what is true, for they are already enduring it.
