'a little bird inside a cage'metephore trap of pursuing beauty and conforming to a beauty standard. Though many women seek to be beautiful for the attention of men and for self approval, Duffy suggests it is a way of oppressing women and trapping them - diminishing them to nothing but animals to be objectified and stared at. The 'cage' symbolises female oppression, not just to Helen who's beauty destroyed her life, but to all women. A 'little bird' also represents fragility and delicateness - juxtaposing the violence of Helen's life.
