I continue to decline requests to state what, to me, constitutes a great sentence. That's because I don't want to influence what other people submit to me. I'm interested in what others consider to be great sentences. One thing I will say, however, is that a famous sentence isn't necessarily a great sentence.
I know exactly what makes a sentence great to me, but I'm not telling—yet. You may look at the sentences I have posted and see if you can figure it out. If you're interested in letting me know what you consider to be a great sentence, feel free to leave a comment below.
