Selden senior had an eye for a picture, his wife an understanding of old lace; and both were so conscious of restraint and discrimination in buying that they never quite knew how it was that the bills mounted up.
It was in just such company, the fine flower and complete expression of the state she aspired to, that the differences came out with special poignancy, her grace cheapening the other women’s smartness as her finely-discriminated silences made their chatter dull.
His real detachment from her had taken place, not at the lurid moment of disenchantment, but now, in the sober after-light of discrimination, where he saw her definitely divided from him by the crudeness of a choice which seemed to deny the very differences he felt in her.
But this lingering semblance of intimacy made her only the more conscious of a change in the relation between Mattie and herself, of a dawning discrimination, a gradually formed social standard, emerging from Mrs. Gormer’s chaotic view of life.
There are no more uses of "discriminate" in the book.
