Free verse minus the free so really just verse..

Once again, mind blown. How can something that is called "free verse" actually have rhythm/structure? I NEVER would have guessed. See, when I write poetry for class, I usually use free verse. And, well I'm not the greatest poet in the world, I kind of just write "freely" and don't really worry about the structure, like just placing sentences that say what I want them to say together. Now I'm pretty sure I've been doing it completely wrong, and I'm pretty sure what I have been writing isn't really poetry at all, more like whatever's in my head written down on a page. The free verse I think of is more like a journal entry or a place where you write down anything, but according to this woman, there is SO much more. Why does everything in poetry have to be so complicated? First the letter sounds and structure of the words, now free verse actually has patterns and such! Its like everything you thought you knew about poetry, like how it is up to the interpretation of the author and the reader, went out the window. But oh well, its interesting enough I guess, and I assume that when I write my free verse poems I might put a little more thought into the actual mechanics behind it.
