Hm, pretty basic, but as you said it was a vent/rant type of piece so those are usually alittle ruff around the edges. I dont know, I really would have like to have seen alot more said... It wasn't even that the structuring was basic, but the content was also extremely simplisitic in the sense that, with the repeating lines and the 4 or so lines of filler it read almost like a childs story. I know it was only a rant but still, there are alot of creative angles you could take to aproach this and describe your feelings. So, not sure if you're just stopping by or are getting into poetry for the long haul, but if you end up writing again try and just think creativily about how you can say whats on your mind... Because originality and individuality in poetry is a huge thing.
