Prompt:  Write a story about an empty glass.

On the table, there were three glasses.  One was half-full, one was half-empty, and one was empty.  The glass that was half-full was always optimistic, while the half-empty glass was a nay-sayer.  Both made fun of the empty glass, for it had no purpose.  The half-full glass frequently admired its contents and its ambition to be the glass chosen for thirst satisfaction.  The half-empty glass lamented about its prospects of ever being chosen and actually fretted about its contents turning sour before consumption.  The empty glass sat still and quietly happy; for it had once been full.  However, its delicious contents had been too enticing for anyone to leave even a partial residue.  The empty glass had fulfilled its purpose and was neither half-full nor half-empty.
