Occasions like the recent one
Remind those who have come of age
That surely there will be a time
When they will move from center stage.
Just how a person leaves the stage
Is often difficult to say
Old soldiers, getting to that point,
They never die, they Fade Away.
Professors somehow do the same.
How it is done, you’ll hardly guess.
For those of us who deal with Waves,
We do not fade, we Evanesce.
