A Poetical Treatise Upon…
… not writing a poetical treatise upon anything…
… as it seems a pointless thing to do.
And, anyway, the thought of a long, boring, and pointless treatise (for that is what I would write – believe me in this) is not doing anybody any favours.
You wouldn’t thank me for writing it, and I would totally appreciate why you didn’t read it.
So, in its place…
short, sweet, to the point,
what could possibly go wrong
writing a haiku?
