a shocking and stormy night by prentice newton

i saw a shocking thing last night that i can’t quite explain.
on the street outside my window, a man stood in the rain.
twas strange to see him all alone on such a stormy night.
who goes out in a thunderstorm and tries to fly a kite?
he tied a key around the string then looked up to the sky.
he showed no fear as thunder crashed then launched the kite up high.
i found the whole thing frightening from the safety of my room.
i watched each flash of lightning with a growing sense of doom.
then a burst of light struck the kite. it glowed as if on fire.
the string lit up as if it were a red-hot piece of wire.
and in the midst of all of this, my eyes beheld the key.
it danced upon the kite string as if filled with energy.
down on the ground, quite safe and sound, the man was dancing, too.
the reason for his happiness? i have not got a clue.
was he just that he survived or was it something more?
my curiosity was sparked, but i’ll never know for sure.
