Answer:
Thank you for providing the poem. Here are the answers to your questions:
1. **Rhyme Scheme**: The rhyme scheme of the poem "Never Give All The Heart" by William Butler Yeats 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 advises not to give one's heart completely in love, as passionate lovers may not value it if they think it's certain and unchanging. The speaker is unhappy because they believe that love, when given completely, fades away from kiss to kiss. The advice is to withhold one's heart and not give it entirely to someone because those who have, in the speaker's view, have surrendered themselves to the "play" of love, which can lead to heartbreak.
4. **Agree or Disagree**: Whether to agree or disagree with the speaker is a matter of personal perspective. Some may agree that it's wise to guard one's heart to avoid potential heartbreak, while others may believe in the idea of giving one's heart fully in love, taking the risk of being hurt for the sake of deeper, genuine connections.
5. **Theme**: The theme of the poem revolves around the idea of caution in love, warning against giving one's heart completely and advocating for a more guarded approach to love.
6. **Imagery**: The poem employs imagery when it describes love as "fade out from kiss to kiss." This imagery conveys the fleeting and transient nature of love, which is a central theme in the poem.
