Dad:

"That's right ...and though I would never contend that I know, I believe that only two-thirds of the angels were singing at our 'In the beginning ...', and you recall that before that, darkness was upon the face of the deep.  I believe God had taken the light away at the fall of the angels ...and the two-thirds awaited to see what God was going to do with the one third who rebelled.  But we shouldn't get hung up on supposing.  The story written for us in the Bible is about us, not the angels."
