Even though it doesn't have a definite rhyme scheme throughout, it does rhyme. I usually would just go back and read something else when I can tell there's not a real structure to the piece, but something about your poem kept me here, and kept me reading. It was very good and SO easy to relate to. It's got a 'realness' to it. I think you did a nice job with it!
I LOVED LOVED LOVED your last three lines!
Great ending :)
