as the last 3 poems i have read this so sad as well... i know the feeling about how someone can nhurt you so much and everyone is blind to the pain.. good job with this poem you caputered everything that needs to be said i think.. well in my opinion you did ..
I love the way you have twisted physical blindness onto an emotional level. I read the title expecting something on the former and it was a pleasant surprise to find such a twist. I like the rhetorical questions but I feel you may have gone slightly over the top. Just a couple would have enhanced the feelings and the power of their delivery but when reading this they feel weakened by the quantity.
