Answer:
Certainly, here are the answers to your questions about the poem "Never Give All the Heart" by William Butler Yeats:
1. **Rhyme Scheme**: The rhyme scheme of the poem is AABBCCDD.
2. **Stanzas and Meter**: The poem consists of four stanzas, and the meter is primarily iambic tetrameter (four metrical feet per line).
3. **Speaker's Unhappiness and Advice**: The speaker is unhappy because they believe that love, when given completely, fades away from kiss to kiss. The advice given in the poem is not to give one's heart entirely to someone. This advice is based on the speaker's belief that passionate lovers may not value a love that appears certain, and those who do give their hearts entirely to love are portrayed as having surrendered themselves to the "play" of love, which could lead to heartbreak.
4. **Agree or Disagree**: Whether to agree or disagree with the speaker is a matter of personal perspective. Some may agree with the caution in love that the speaker suggests, while others may believe in the idea of giving one's heart fully in love, even if it carries the risk of potential heartbreak. It depends on one's personal approach to relationships and love.
5. **Theme**: The theme of the poem revolves around the idea of caution in love and the transience of romantic feelings. It highlights the fleeting nature of love and the speaker's advice to guard one's heart from the potential pain of love.
6. **Imagery**: An example of imagery in the poem is when it describes love as "fade out from kiss to kiss." This imagery conveys the idea that love is fleeting and doesn't remain constant, and it uses the sensory experience of kisses to illustrate this concept.
