The other night I met Mark Twain
I passed the invisible frontier into  a
Large area like a deserted fairgrounds
In the darkness of the coming night.  
There were others  there, not many as
Dark figures passing when I came up
To him, as to an old acquaintance not
Seen for a while.  I said this place quivers
As between day and night- like any moment
It will change and we will not be here at all.
Just at the end of twilight it was.that He said:
Yes' but where else could we meet-That did
Seem to answer all my questions; and I woke
Knowing I had been somewhere else, a place
Between where something more and some-
Thing less can coexist in a fragile balance.
Like the attic of all beloved memories -not too
Far away to travel to when we must know still
They are, a place where they live and are real.
