The speaker rejects the usual Valentine's gifts and offers an onion instead, as a truthful image of love that brings beauty, tears, possessiveness and danger.

How to use the lesson's key quotations in an essay, with a short worked paragraph.
Key quotations: 'Not a red rose or a satin heart', 'I give you an onion', 'It is a moon wrapped in brown paper', 'like the careful undressing of love', 'It will blind you with tears / like a lover', 'a wobbling photo of grief', 'I am trying to be truthful', 'Its fierce kiss will stay on your lips', 'Its platinum loops shrink to a wedding-ring', 'cling to your knife'.
Form: free verse in stanzas of uneven length, one-line stanzas such as Here and Take it, a speaker addressing the lover directly, and an extended metaphor that darkens towards the last word.
Context: Carol Ann Duffy (born 1955), whose collection Mean Time (1993) won the Whitbread Poetry Award and who became the first woman Poet Laureate in 2009; and the Valentine's Day customs of flowers, cards and hearts that the poem rejects.
Compares well with: Sonnet 43 (contrasting declarations of love), i wanna be yours (unconventional images of devotion), 1st Date – She and 1st Date – He (truth and pretence) and Love's Dog (the pleasures and pains of love).
