I'm the person who will make the wiredest noise for no reason at all at anytime in the day--- I talk deep. I completely skip small talk, get to know the person, then find out their entire life. (And tell them mine.) and this is how you get hurt.
I can't even say how true this is. A friend can constantly tell you how awesome they think you are, how much they love you, and how you're one of their favorite people in the world, but just a few minutes later your brain is saying "Don't bother them, they don't want to deal with you and you'll just annoy them."
