penny nails

So I keep writing prose
and my eyes get caught 
by a gap that should be 
there 
but isn't or ought it not 
be? But it isn't! 

I want to aver or demur 
and I've got just the sign
and spur: it's my buddy 

the comma! Don't tell me 
I'm gonna! I got to get in 

there and pound those nails
'cause I'm driven somehow 

to break up my thought. I 
perceive there's a much
needed gap that I have 

the cents to have bought
