“(They) crave to know where the door is,
And all that so many ever find
Is only the wall where a door ought to be.
They creep along the wall like blind men,
With outstretched, groping hands.
Feeling for a door, knowing there must be a door,
Yet they never find it…
So I stand by the door.”
from: Samuel Moor Shoemaker, I Stand by the Door
