Cathedral by Raymond Carver

In the story Cathedral by Raymond Carver the author demostrated the characters relantionship and how they communicated. At the beginnig of the story the husband seems to be not sure about the blind man coming to his house to see her wife. Once the wife introduced "Robert" the blind man to her husband, the husband started to speak sarcams words to any of the conversations they had. In the middle of the story I thought that the husband was jealous. But when they started to know each other all was different. I think that as a human being cannot be rud with a person if you don't know him/her very well. I think we have to get to know the person and then decided and come with their own conclusion.
