What is a short summary of the story, Nobody’s Business, from the collection, Unaccustomed Earth?

In “Nobody’s Business,” Sang is in an emotionally abusive relationship with an Egyptian man named Farouk, who is seeing more than one woman. Sang’s roommate, Paul, has fallen for her. While Sang is away visiting relatives, an intoxicated woman named Deidre calls the apartment looking for Farouk. Paul discovers Farouk’s womanizing, which Sang later accuses Paul of making up to get her to dump Farouk.

Only when listening in on a conversation with Deidre does Sang learn the truth. She confronts Farouk with Paul, and the two men wrestle until Paul gains the upper hand and Farouk flees to his apartment. Brokenhearted, Sang leaves for London. Some months later, Paul sees Farouk and Deidre on the street. Farouk tells Paul that he is lucky no charges were pressed for the fight.
