The Leaf Poem by something changing

a leaf.
such a simple thing.
only one insignificant
among billions on one tree.
once its season is up, it falls.
does it know it's falling?
does it care?
does it know that
that's its purpose in life,
and therefore doesn't question
its inevitable float to the ground below?
does it enjoy its duty
of supplying life for the tree?
does it care about the tree at all?
does it have insecurities?
if so, what kind?
does it worry
about what shade of green it is?
or, is it happy being itself?
and when it falls,
is it scared?
is it always afraid
that it will fall sooner than it should?
does it ever worry?
or does it just accept its fate?
when it falls,
does it wish it didn't have to?
does it desire to be
back in the tree again?
does it matter?
