That Old Sweetheart of Mine by Ring Lardner

Stella Crane had a maid, but preferred answering the telephone herself when she was at home, which was most of the time. Calls came infrequently and were welcome -- an invitation to go to the theater with the Smalls, or to play bridge at Bess Cooper's, or to dine with the Fields. Aside from two or three of her husband's business acquaintances, whom he had had at the house for evening conferences, the Fields, Smalls and Coopers were about the only people in New York Stella had met.

There was nothing wrong with her or Ralph; they both dressed well and behaved respectably, and Stella played a fair game of contract. But they were not asked out much because Ralph, a patent lawyer, did a great deal of work after hours and was anything but hospitable. If you refrain from inviting people to your house, they are going to invite you less and less often to theirs.
