If you engage in a conversation of any length, basically anything after small talk about the weather, the crazy starts to rear it's head. Maybe we've grown so accustomed to the "crazy talk" that it becomes less and less recognizable as crazy talk.
No sense in going into examples here. I've been swimming in the crazy lately, and I've engaged in it too. Yes, I too can do the crazy talk, the crazy walk. But then I can sort of retreat into a dark corner of my head and realize that what is said, what is believed is crazy! It has permeated all areas of human behavior.
Beliefs: religious, political, social... Totally Over the Bend Nuts!
