As I wait...

I examine my hands to discover a tar like grit beneath the nail on my left index finger
I enlist the pointed corner of my opposing thumbnail to chisel away the unwanted soot.

The exercise proves therapeutic - even gratifying
As when eliminating the descending alien attackers in an ole school video game
Like crossing off an eight-letter word (having a percussion sound) for boredom - in a crossword puzzle

After a moment of review all nails check out positively
Then, with one last stroke of my thumbnail my impulse to groom is well satisfied
And I rise from the doldrums just as the light changes to green
