Listen: I am ideally happy. My happiness is a kind of challenge. As I wander along the streets and the squares and the paths by the canal, absently sensing the lips of dampness through my worn soles, I carry proudly my ineffable happiness. The centuries will roll by, and schoolboys will yawn over the history of our upheavals; everything will pass, but my happiness , dear, my happiness will remain,in the moist reflection of a street lamp, in the cautious bend of stone steps that descend into the canal's black waters, in the smiles of a dancing couple, in everything with which God so generously surrounds human loneliness.
Vladimir Nabokov, Selected Letters, 1940-1977
