"I might show facts as plain as day: but, since your eyes are blind, you'd say, 'Where? What?' and turn away"

This quote by Christina G. Rossetti is a commentary on how individuals can be so blind to the reality that is right in front of them. It is suggesting that even if somebody were to present facts that are as clear as day, those who are blind to the truth would not have the ability to see it. They would ask concerns such as "Where? What?" and after that turn away, unable to accept the truth. This quote is a tip that people can be so persistent and reluctant to accept the fact, even when it is right in front of them. It is a suggestion to be unbiased and to be happy to accept the truth, no matter how difficult it may be.
