Invention

Tonight the moon is a cracker,
with a bite out of it
floating in the night,
and in a week or so
according to the calendar
it will probably look
like a silver football,
and nine, maybe ten days ago
it reminded me of a thin bright claw.
But eventually --
by the end of the month,
I reckon --
it will waste away
to nothing,
nothing but stars in the sky,
and I will have a few nights
to myself,
a little time to rest my jittery pen.
