A Parody of You in Rigor Mortise Blue.

It was pouring down with sunshine when I wrote this effort. I was
frowning for England and could hardly see the text on my monitor for
the glare. Flawless summer days have a habit of pissing me off, hence
the following?

A PARODY OF YOU IN RIGOR MORTISE BLUE.
sneak

It's a skill I have acquired -
over countless days of dread.
I am an expert in my field,
I imitate the dead.
Years of common practise -
have sharpened my game-plan.
I am easily the worlds' -
most apathetic man.
I can sleep through most occasions.
Perfect days are mine to waste.
Blue skies on calm horizons -
only contradict my taste.
I am happy in this prison -
of pallid crawling skin.
This frown, born of the sunshine,
hides a satisfying grin.
My vicious cold appearance -
is blatant on my part.
I would like to say I'm human,
but I haven't got the heart.
A morbid fascination -
with the smiles people wear,
contorts my ashen face -
in to a collage of despair.
So alien a concept,
this journey that we face.
I've searched for the instructions,
but cannot find a trace.
I would like to say I'm human,
but I haven't got a clue.
Implausible, my efforts -
to grin the way you do.
Hopelessly confounded -
by the meaning of it all.
Your achievements emphasized -
by the swiftness of my fall.
