Some people don't perceive things as they really are. They see them as they want them to be. Then there's people that just shoot off their mouth without thinking and they'll believe what they're saying. It doesn't take long for it to become truth to them.

I was married to someone like that a long time ago... and I know someone now that does that all the time. You can't believe a word that comes out of their mouth... yet they believe it's the truth.
