How little we have, I thought, between us and the waiting cold, the mystery, death--a strip of beach, a hill, a few walls of wood or stone, a little fire--and tomorrow's sun, rising and warming us, tomorrow's hope of peace and better weather . . . What if tomorrow vanished in the storm? What if time stood still? And yesterday--if once we lost our way, blundered in the storm--would we find yesterday again ahead of us, where we had thought tomorrow's sun would rise?

Summer is the worst time of all to be alone. The earth is warm and lovely, free to go about in; and always somewhere in the distance there is a place where two people might be happy if only they were together. It is in the spring that one dreams of such places; one thinks of the summer which is coming, and the heart dreams of its friend.

What is it which makes a man and a woman know that they, of all other men and women in the world, belong to each other? Is it no more than chance and meeting? no more than being alive together in the world at the same time? Is it only a curve of the throat, a line of the chin, the way the eyes are set, a way of speaking? Or is it something deeper and stranger, something beyond meeting, something beyond chance and fortune? Are there others, in other times of the world, whom we should have loved, who would have loved us? Is there, perhaps, one soul among all others--among all who have lived, the endless generations, from world's end to world's end--who must love us or die? And whom we must love, in turn--whom we must seek all our lives long--headlong and homesick--until the end?
