This a poem from Birthday Letters about the years Hughes spent with Sylvia Plath. I love this poem despite its occasional tone of subtle cattiness and overall tone of bewildered irony. Even though Hughes is often considered the bad guy in their relationship there is also a sense that theirs was a fateful bond especially when the grief and longing come through these lines. Sylvia as a the ghost here is so fragile that it took me three readings before she fully materialized. I enjoy the image of the lost wedding gift as a grave marker in the last stanza. The anger and sadness in 'She has forgotten/She cannot even remember you' is substantial. This is a very genuine reaction to the death of important person in Hughes' life.
