Lightning strike,a bolt from the blue,takes out in an instant that thing that person that idea you were so certain about ;after this the deluge and the raging floodwaters wash away that which you had without question called permanent,proving it to be,at best,an error of judgement,at worst,self-delusion.But then as the skies clear you may see that the lblasted aside the lightning bolt has in fact blown a hole in the wall which imprisoned you,and that the cloying oppressive stultifying present has given way to a fresh and refreshed and shining future you never dared to dream of.
