The Age of Innocence

by Edith Wharton

What could he and she really know of each other, since it was his duty, as a "decent" fellow, to conceal his past from her, and hers, as a marriageable girl, to have no past to conceal?

At length she said: "I believe it's because of you." It was impossible to make the confession more dispassionately, or in a tone less encouraging to the vanity of the person addressed. Archer reddened to the temples, but dared not move or speak: it was as if her words had been some rare butterfly that the least motion might drive off on startled wings, but that might gather a flock about it if it were left undisturbed.
