The Tragedy of Mister Morn, V. Nabokov

"You will leave; we'll forget one another;
but now and then the name of a street,
or a street organ weeping in the twilight,
will remind us in a more vivid and more
truthful way than thought could resurrect
or words convey, of that main thing which
was between us, the main thing which
we do not know...
And in that hour when the soul
will sense the charm of past trifles—
the soul will understand that in eternity all is eternal:
the genius' thought and the neighbour's joke,
the bewitched suffering of Tristan
and the most fleeting love."
—The Tragedy of Mister Morn, V. Nabokov
