Signs, portents, omens. The hero is awakened by the herald, a harbinger (or two, or three). Gandalf sparks Frodo, Hagrid awakens Harry Potter, or Pooh to piglet The shady one, the mysterious one, the edgy one, is the harbinger, the one who calls or perhaps, the one who points. Some are explicit, some are covert, but whichever, whomever, they unveil the beginning of a path, a journey, sometimes an adventure. We all need a harbinger ot two in our lives, someone who will spark the journey, the adventure, the next step. And, in our own way, we all need to be a harbinger for someone.
As Winnie the Pooh says:-
"I knew when I met you an adventure was going to happen." Winnie the Pooh (A.A. Milne)
