Then I suddenly had the most tremendous feeling of the pitifulness of human beings, whatever they were, their faces, pained mouths, personalities, attempts to be gay, little petulances, feelings of loss, their dull and empty witticisms so soon forgotten: Ah, for what? […] Suppose we suddenly wake up and see that what we thought to be this and that, ain’t this and that at all? I staggered up the hill, greeted by birds, and looked at all the huddled sleeping figures on the floor. Who were these strange ghosts rooted to the silly little adventure of earth with me? And who was I?
