As I stand on the mountaintop as the great bird approaches
She is small in my sight but grows larger on approach
until I am blessed with the full sight of her graceful wings, proud countenance and good company.
All too quickly she grows small again on the horizon and disappears from view and I call out "there, she's gone".
But there are other mountaintops beyond me and at the precise moment when I note the great bird's departure from my view,
I know there are new eyes taking up the sight of her and fresh voices calling out "here she comes".
