Her adherence to social order is what enables her to cope with the challenges of a changing world around her. Part of this involves her duty as a mother. She is attentive to the needs of her children. Yet, in this capacity, she understands the changing nature of the world, her world, and finds herself unable to articulate a position in which this change needs to be altered.
