Read the last stanza. Do you think Amanda is sulking and is moody?
No, Amanda is not actually sulking or moody. The speaker misunderstands her silence and withdrawal as sulking. In reality, Amanda is escaping into her imaginative world—where she is a mermaid, an orphan, and Rapunzel—to find the freedom and tranquility she lacks in her real life.
The constant nagging and instructions from the speaker make her withdraw into herself. Her quietness is not moodiness, but a natural reaction to being constantly controlled and a deep yearning to be left alone.
Explanation
The last stanza shows the speaker accusing Amanda of sulking and being moody. However, reading the whole poem reveals that Amanda's silence is not moodiness but a retreat into her imagination to escape the constant nagging. She imagines herself as a mermaid, an orphan, and Rapunzel—figures of freedom and peace—which contrasts with her restrictive reality.
