He was, at that time, a remarkably fine young man, with a great deal of intelligence, spirit, and brilliancy; and Anne an extremely pretty girl, with gentleness, modesty, taste, and feeling. Half the sum of attraction, on either side, might have been enough, for he had nothing to do, and she had hardly anybody to love; but the encounter of such lavish recommendations could not fail. They were gradually acquainted, and when acquainted, rapidly and deeply in love. It would be difficult to say which had seen highest perfection in the other, or which had been the happiest: she, in receiving his declarations and proposals, or he in having them accepted. (4.1)
While the novel may ultimately be a romance, it doesn't shy away from cynical views of love: just like Louisa and Captain Benwick, a major factor in Anne and Wentworth's great love affair is that they're available, bored, and living in the same area. Of course, once they've fallen in love, they never meet anyone else to compare, but that first fall seems founded on shaky ground – and yet, the novel suggests, all romance works that way.
