Green And Yellow

The grass is green
everyone knows
the hay is yellow
that all know
what is new ? in that
you would ask. with a shout
the fresh one being green
and the dried turning yellow
shows a real follow
that things when are new
look beautiful and gleaming
catching the eye all the more
when they be let like that
for months and years together
they transform into a substance of mellow
with a maturity all round
modest and charming as well
which is old has also a value
that being young commands a fair chance
there  goes the way of life in a circle
all great and good  on the round.
