But what???

Let me have my say, poetically, and maybe I'll try writing a ghazal 
tomorrow.  My understanding of that form is that it expresses the distilled 
idea or emotion, i.e. has a haiku like quality, as well as implied or overt 
teasing, and riddles may be included. But, for today:

It's snowing again.
I'm supposed to write a poem today.
My pen is poised
but I've no idea...What to say?

For discipline,
it's good for practice, this poem a day.
Helps wake the brain.
But my only thought is a refrain:

But, but, BUT... 
(But WHAT?!)
