This poem starts in the boast: "When I take my girl to the swimming party...," continuing with the first juxtaposition of male with female genders, for the boys "tower and bristle," suggesting something naturally intimidating is inherent to the male gender. This is followed by the description of the girl, who is "smooth and sleek," an alliteration that denotes the use of diction, for the contrasted descriptions also have a set syllable pattern: the description of the boys uses two syllables per word in order to create a harsh, rough connotation, and the girl's description flows smoothly in each of the single syllable words. The next description incorporates the first usage of the mathematical metaphor/symbol, and contrasts the previous description of the girl, for her body is "hard and indivisible as a prime number," adding a independent nature to the character of the girl, and strengthening her role as a strong and feminist model for the beginning of adolescent maturity.
