Here I go again and I do not know where my narratives come from....overactive imagination I presume....these geese know about the spirit world that exists all around us. They know of the pirate, now long dead, lurking in the marshes around their home. They also know of the one with nature that the Native American has with the earth.
Personally, I believe that dead is dead and that is the end of it. So for me to be discussing the spirit world is a bit much for me to ponder! :-)
