At the end of Ch. 23 Jim tells as story about his daughter. What is significant in that story and what does it reveal about Jim?

jim tells the story of his daughter being deaf, but he doesn't know right away that she is deaf. his daughter becomes sick, and when she is better she is deaf. when he tells her to close the door and she ignores him he doesn't know that she cant actually hear him. he hits her and when he realizes that she is actually deaf he feels awful. this is important because firstly is shows that jim has a family that he loves and cares for. and second it shows that jim has a hard side; although, his softer side is much more predominant.
