What can a pencil do for all of us? Amazing things. It can write transcendent poetry, uplifting music, or life-changing equations; it can sketch the future, give life to untold beauty, and communicate the full-force of our love and aspirations.

Surely some revelation is at hand.
Metaphor 
All glory is fleeting.
And its markings can be readily erased.
The pencil, a tool that should be in all our toolboxes !
