Sentences are not different enough to hold the attention unless they are dramatic. No ingenuity of varying structure will do. All that can save them is the speaking tone of voice somehow entangled in the words and fastened to the page for the ear of the imagination. That is all that can save poetry from sing-song, all that can save prose from itself.
Robert FrostThe middle of the road is where the white line is - and that's the worst place to drive.
Robert FrostWhen the spent sun throws up its rays on cloud And goes down burning into the gulf below, No voice in nature is heard to cry aloud At what has happened. Birds, at least must know It is the change to darkness in the sky. Murmuring something quiet in her breast, One bird begins to close a faded eye; Or overtaken too far from his nest, Hurrying low above the grove, some waif Swoops just in time to his remembered tree. At most he thinks or twitters softly, 'Safe! Now let the night be dark for all of me. Let the night be too dark for me to see Into the future. Let what will be, be.
