Any interpretation of meaning is a 'reading', therefore at least ONE reading is necessary. My point is you can broaden your discussion if you consider the poem in more than one way. This makes your poems more flexible in terms of answering a question. Don't place the focus on the fact that it's a 'different reading', but rather the fact that her deft poetry actually reflects many aspects of her life. Her economical language is her trademark.not sure, but i don't think readings are necessary.
