The key to the second stanza in the poem "Aunt Jennifer's Tigers" is in the third and fourth lines,
"The massive weight of Uncle's wedding band
Sits heavily upon Aunt Jennifer's hand."
These lines express the idea that Aunt Jennifer's marriage is not a happy one. The heaviness of the wedding band indicates that she is dominated by her husband, and the fact that the wedding band is described as belonging to Uncle rather than Aunt Jennifer herself gives further proof that Aunt Jennifer's life is not her own. The emotions evoked by the second stanza include nervousness, tiredness, and dissatisfaction. Aunt Jennifer's fingers "flutter," indicating unease, and even "the ivory needle," the tool of artistry which she obviously loves, is difficult for her to pull, indicating weariness. The sense of the stanza as a whole communicates unhappiness and a feeling of being overwhelmed by the weight Aunt Jennifer is forced to carry. Marriage is not a happy condition for her, and though she has her art, the heaviness of her situation overshadows even her life's joy.
