Last week, I happened to hear Billy Joel's "She's Always a Woman" while at the store, and it occurred to me how parallel two of the lines are: "Oh--and she never gives out / And she never gives in." Except for the "out" and "in" (prepositions acting in verb-adverb combinations with "give"), which are opposites, the lines are virtually the same. It's interesting that those two words can provide such an opposition while - individually - the lines are saying distinct things. So you can understand that "she never gives out," "she never gives in," and - like the language used to describe her - she's seemingly contradictory and embodies opposition. The next line ("She just changes her mind") confirms this.
I looked in the liner notes of The Stranger (the album on which "She's Always a Woman" appears) to find the lyrics (it's faster than transcribing them myself, although I did notice some small discrepancies between the printed lyrics and the sung lyrics), and I found two other similar instances. The first is the first two lines: "She can kill with a smile / She can wound with her eyes." Both lines are structured the same way and indicate the woman's hostility. Later, there're the lines "She is frequently kind / And she's suddenly cruel," which - along with their structural parallelism - demonstrate her erratic nature. However, I don't think either of these pairs of lines has the same sort of implication as "Oh--and she never gives out / And she never gives in."
