Man is flying too fast for a world that is round. Soon he will catch up with himself in a great rear end collision.
James ThurberEvery man is occasionally visited by the suspicion that the planet on which he is riding is not really going anywhere; that the Force which controls its measured eccentricities hasn't got anything special in mind. If he broods on this somber theme long enough he gets the doleful idea that the laughing children on a merry-go-round or the thin, fine hands of a lady's watch are revolving more purposely than he is.
James Thurber
