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.
The line-storm clouds fly tattered and swift, The road is forlorn all day, Where a myriad snowy quartz stones lift, And the hoof-prints vanish away. The roadside flowers, too wet for the bee, Expend their bloom in vain. Come over the hills and far with me, And be my love in the rain.
At bottom the world isn't a joke. We only joke about it to avoid an issue with someone, to let someone know that we know he's there with his questions; to disarm him by seeming to have heard and done justice to his side of the standing argument.
