Poetry and me

For AP English we are having to read poetry and I'm somewhat getting it but I'm not getting it at some points as well.  Because I'm getting what he saying a little bit about how a sonnet is 14 lines but I am not really understanding about how the poem flows aabb ccdd and so on. It just doesn't make any sense to me about how to do that with a poem. It makes me wonder if very poem is supposed to be like that or if it is just a basic foundation for a poem. I am starting to like poetry more I just have the feeling that I don't know how the structure of a poem is set up. I can analyze a poem pretty well I think and I can usually get what the poem is about. Just the problem that I'm having with poetry is what we are learning in class because I am only really understanding half of what I am being taught and the other stuff is just going in one ear and out the other. I hope that I get poetry in the end because after working with it in class I don't dislike it as much as I used to. I am happy that I am starting to like poetry because I believe that mu teacher is right when he says that poetry is good for our lives because it lets us express ourselves in ways that we may not be able to.
