"you are stained, stained to perfection" (Heaney 47).

I had to read the poems a few times to get a better understanding. I finally realized that the narrator is admiring a female from a far first, and then I believe he moves closer to her. The poem is about love and the image you personally have of your significant other. In the first part, he compared her to nature as he was watching her interact within nature at the same time. He painted a picture of elegance. In the next part, he talked about actual objects such as a dryad, chestnuts, the moon, and moby-dick rather than just nature. He continued to put this female on a pedestal. In the third part, he stated everything that she is not, but that she is even better than. Lastly, he actually interacts with the female physically. He put another "vaccination" mark on her but proceeds to be content with it. He is content with it because regardless of all the flaws she may have, the narrator still sees perfection in his eyes.
