When the narrator of Raymond Carver's short story "Cathedral" offers his wife's friend Robert a drink, Robert replies, "Bub, I'm a Scotch man myself." The narrator is irritated at being called "Bub" by a man he has only just met, but this is the nearest he comes to being named throughout the course of the story. The narrator does not call his wife by name either, meaning that Robert is the only named character.
The narrator mellows over the course of the story but is initially an unsympathetic figure and is selfish and insensitive in his behavior to his wife. His wife never calls him by name; even when introducing him to Robert, she simply calls him "my husband." This gives the reader an indication of the tension between the two of them. Robert's name is mentioned frequently, and even his wife, who is dead, is given the name Beulah. In fact, the narrator's wife repeats Robert's name with conspicuous warmth and insistence:
"You look distinguished, Robert," she said. "Robert," she said. "Robert, it's just so good to see you."
This repetition of Robert's name, together with the attention she lavishes on her guest, is a stark contrast with her failure to mention her husbands name at all, as well as being in accordance with her sharp, irritable manner towards him.
