The law of nature is alternation for evermore. Each electrical state superinduces the opposite. The soul environs itself with friends, that it may enter into a grander self-acquaintance or solitude; and it goes alone for a season, that it may exalt its conversation or society. - Ralph Waldo Emerson
It is the custom on the stage in all good, murderous melodramas, to present the tragic and the comic scenes in as regular alternation as the layers of red and white in a side of streaky, well-cured bacon. - Charles Dickens
