I usually only write in ryhme, so I would appreciate your critiqueing this foray of mine into untested waters!
The rain falls softly against my window pane.
Tentative, at first, like a hesitant lover,
not sure his presence is welcome,
Then, becoming bolder,
not wanting this moment to pass him by!
Just moments before,
the azure blue sky
noted a whisper of gossamer pillows,
playing tag around the sun,
and had abruptly put an end to their frivolity!
Like a stern parent,
he summoned them together,
as in a war council,
to chastise them for their playfullness!
Thunder, like a mighty beast stalking its prey,
rolls across the sky with a mighty roar,
while lightning, with its kaleidoscope of colors,
streaks across the heavens
to add a reprimand to the proceedings!
After a few moments, exhausted and spent,
the sky once again returns to its former splendor
and pays homage to the sun!
Your poem is beautiful and I think you could just as easily write another one from it.
