One world and then another, running like a chain. One world treading on the heels of another world that plodded just ahead. One world's tomorrow, another world's today. And yesterday is tomorrow and tomorrow is the past. Except, there wasn't any past. No past, that was, except the figment of remembrance that flitted like a night-winged thing in the shadow of one's mind. No past that one could reach. No pictures painted on the wall of time. No film that one could run backward and see what-once-had-been.
