Do you ever get the feeling that your'e running out of words
I know it sounds ridiculous and even quite absurd
When you think youv'e written everything
and nothing else will rhyme
I sometimes get that feeling
when I write from time to time
Do you ever feel that freeform
has been taken from a book
a paragraph or sentence
with no meaning and no hook
That's difficult to understand
there aren't any signs
I sometimes come across this
when I read from time to time.
Charles M. Moore
