It was principally because (just as increased tension upon a cord or accelerated vibration of a nerve produces a different sound or colour) it gave another tonality to all that I saw, introduced me as an actor upon the stage of an unknown and infinitely more interesting universe; that handsome girl whom I still could see, while the train gathered speed, was like part of a life other than the life that I knew, separated from it by a clear boundary, in which the sensations that things produced in me were no longer the same, from which to return now to my old life would be almost suicide. To procure myself the pleasure of feeling that I had at least an attachment to this new life, it would suffice that I should live near enough to the little station to be able to come to it every morning for a cup of coffee from the girl.
