Билли Коллинз. Изобретение

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.
