What you believe determines how you behave ... For example, one time, when my oldest son Sam came running in, throwing up into his hands ... *blechghchgh* and he said, "Daddy, Bookie is eating his poop!"  So I ran past Sam who was throwing up in his hands and ran into the room where there was little Bookie, my second son, with dark stuff all over him.  And I threw up, not in my hands.  It was like, violent, vomiting.  It went well beyond my hands.  It went everywhere.  So Sam's in throw-up, I'm in throw-up, and so we did the only thing we could do, which was call for Mom ... She came busting in, by all the throw-up, and there was Bookie with the dark stuff.  And she just went up to him and wiped off the smudged Oreo cookie which was on his face.  Wasn't poop; it was Oreo cookie.  But we believed it was poop, and so it affected us as if it were poop.
