It's a characteristic of my writing that I sometimes like a stream of very short "sentences", some with only one word. An example written just for this thread (I'm not trying to get around the ban on posting your own work until two weeks is up - honest) would be something like this. OK - the content of that is non-fiction. But that is the kind of structure I like to use occasionally. According to "rules" that I have seen, if you ever have four lines with fewer lines than sentences, you have choppy sentences. But as in the above example, I will occasionally have four "sentences" in a single line. I could rewrite this to be: The first sentence isn't grammatical (I think), but rewriting it further takes it too far from the first example. To me, the second version lacks the rhythm given by the longer pauses for sentences. It's not as punchy. And there's less contrast with the longer sentences that follow. I'd very much like to hear the opinions of other people concerning this.
