Flash in the pan.

The wildness that arrives, so elusive in its quest for mortal zest, rushes past me like a broken beam of light.  Basking in the radiance that it leaves behind, I'm charged again, and wonder what had drained me before.  A token of abject misery bounces and rolls down the stairwell and comes to rest at my feet.  But like a mower out of gas, I pull and pull the cord, and all it does is sputter.
