Facts by our side are never sudden

Facts by our side are never sudden
Until they look around
And then they scare us like a spectre
Protruding from the Ground -

The hight of our unknowing portentous Neighbor
We never know -
Till summoned to his recognition
By an Adieu -
Adieutill when for whence thewise sage cannot Conjecture
The bravest die
As ignorant of their resumption
AsCowards do - you or I -
