A poem on irritation by inky

A rant on Flat Pack Furniture
I
The planning was meticulous
you bought it from the store
the storage unit of your dreams
that gave space and so much more
It came with an Allen Key
II
Into the empty room you stood
and looked at the jigsaw bits
no standard screws for this job
you have to use what fits
Clue…it came with an Allen Key
III
So you start with pre assembly
wood dowels at each end of the planks
another piece of the puzzle
you are grateful and give thanks
No need for an Allen Key
III
But then the magma bubbles
as you’re looking in the sealed bag of screws
there’s something that you need right now
and you can’t come to terms with the news
Where’s the Allen Key?
IV
It seems that the item needed to fix part A to B
has grown itself some handy wings and decided to flee
what’s annoying is that others you would use instead
do not fit the holes drilled in the screw head.
SO….WHERES THE ALLEN KEY ?
V
Modern day furniture – “so easy to handle”
burning both ends of your patience’s candle
so you hammer the screws to the holes there in three
