   Friend is so sad!  Picks up severed head, goes to police station.
   Delivers head to police officer with explanation and the message, "I'm
   only trying to support you.  I don't need a hug if you don't want one.
   Can you hear that I want to give you what you need?"
   Returns to home to find it burned down.  The ashes of all their

   it's like to be me."
