For the Want of a Nail Allegory

For the want of an nail allegory of the day
By Tomas d’Espósito Muller aka El Tomi
The idiom goes on from the loss of a horse
And the defeat in the ensuing battle
Idioms take root in common sense
And need few words to carry their message
My Kingdom for a horse is the next step
As Richard may have thought
The third is a charm…
When will we realise that the war is lost ?
