Rules unto a poet

As conduct is to fall on us now like snow did unto the caveless Neanderthal
Etiquette rains down and floods us out like Noah's cynics
These rules manners and modes overcrowd us day after day
From the way you walk in the park to the full blown picnic

The way I word the night has been likewise described  a million times
The digestion of words and the regurgitation
Rules that I've broken aren't original rhymes
Though my poetry never danced to expectation

These should's and have to's are supposed to even me out
Though imbalance in the written word is what it's all about
The form suggests it's not my head but my chest
Throwing forbidden ink into your eyes, verse blessed!
