There are a lot of thinking points in this story. In my opinion, the author wanted to convey readers how the narrator’s thinking about the blind man was changed through this story. In the first time, the narrator believed that the blind man was totally different human being because he can not see anything, however, the narrator was surprised at him when he saw the blind man first time because his appearance was not so different as usual people. At first, the narrator felt big jealousy toward blind man, so he was mean to the blind man because his wife and the blind man seemed got along well. However, the narrator’s opinion about him was changed gradually as the story going. At first, the narrator was consumed by jealousy, however he opened his heart to him after drawing the cathedral together, also he learned a lot of things from blind man.
