My thoughts on this are a lil shaky. To me, it seems as if the girl has locked herself into a state where she doesnt want anyone but herself. Then a man comes and looks beyond the closed sign, and he cares for her, breaking through those bars that were keeping her locked inside. This is what I think, I'm not sure if it is correct or not...Sorry if I'm not. But I liked this, flow, structure, scheme and wordplay was all nice. Great job. Keep it up.
