Mary and Ann are so well behaved that nothing happens to them, and that is exactly the point. Jane Taylor's poem presents two sisters who never quarrel, never grab, never sulk and never need to be told twice. Its central idea is simple and openly stated: real kindness means being willing to "give up" your own way, and children learn it best by copying good examples. The last stanza says so outright, inviting the reader to "try their example to mind" and to be "obliging and kind."
What makes the poem interesting is how much of its goodness is described through negatives. The girls are "not either sullen or mute," they "seldom or never" dispute, and such disagreements are "never known." The word *never* returns in the third stanza, and the fourth stanza opens a line with *Nor*. We learn what the sisters are like almost entirely by hearing what they are not. As a result, the bad behaviour keeps creeping into the poem. We meet quarrelling, striking, greed and squabbling over chores, all conjured up only to be dismissed.
The poem's one vivid picture belongs to the villain. Other children are "greedy" and would "eat in a corner with nobody by." That image of a child hunched away from the family, shielding a treat, is more memorable than anything the sisters do. By contrast, Mary and Ann are barely drawn at all. They have no faces, no differences, no voices. The poem speaks of "one" and "the other," or "each," or simply "they," so the pair behave almost like a single child. This vagueness suits the poem's purpose. They are meant to be a pattern, not people.
The sound of the poem keeps this lesson light and easy to remember. Each stanza is built from rhyming couplets (*Ann/can*, *mute/dispute*, *like/strike*), and the lines move with a bouncy, galloping rhythm of two unstressed syllables followed by a stressed one: "Two GOOD little CHILdren, named MAry and ANN." It is a rhythm made for reciting aloud. Sometimes the rhyme seems to drive the sense. "As good girls always can" is a slightly odd phrase that exists largely because it rhymes with *Ann*, and it makes the girls' happiness sound like a matter of course. Elsewhere the couplets work well. In the second stanza, a question ("Must they quarrel and strike?") gets a sharp, one-word answer ("No"), like a teacher quizzing a class.
Authority sits in the background throughout. The sisters respond to "papa or mamma" by running "immediately," and the stanza ends on shame: they "would be ashamed to behave themselves so!" The exclamation marks, here and in the greedy-child stanza, give the narrator a slightly scolding tone. Goodness is tied to obedience and to the fear of looking bad, as well as to generosity. The final stanza adds a pun on "mind." To "mind their example" means to notice it, but it also carries the sense of minding, as in obeying. The repeated word *own* ("give up her own," "give up their own way") shows what is being asked of the reader: to surrender what is yours.
Today the poem is easy to smile at, because no real pair of sisters is this perfect, and children have always noticed that. Its significance lies partly there. It is a clear, compact example of verse written to instruct, where plot, character and surprise are sacrificed to a single lesson. It also shows how a moral poem works on its audience, through repetition, catchy rhyme and the quiet pressure of comparison. Jane Taylor is best remembered for "Twinkle, Twinkle, Little Star," and the contrast is worth noticing. That poem invites wonder, while this one invites good manners. The nursery-rhyme music is the same, but here it carries a lesson in how to behave.
