poeming on a november theme

And now the greens have vanished
browns dominate the sky, of the trees
that still have leaves; only two weeks ago,
green was still everywhere, hornbeam and ash
holding on while birch and beech yellowed,
lesser flames of scarlet oak than year's past
(leaves need cold to turn the brightest)
and it all reminds me of how fast
time moves, how quickly leaves
change, how you blink and turn forty
and yet how each moment forces you to stop
and wait, patience in the timing,
knowing that the leaves only
change once, every year, every year,
every year, this cacophony of life
