Read the excerpt of a conversation between Sadako and her father, Mr. Endo, from "Morning Rain.” " Sa , I think I’ll visit with the Iwanagas this afternoon. I didn’t see them the last time. Then there’s a movie I want to see at the Fuji-kwan. Don’t expect me for supper. I’ll eat something down in Nihon-machi.” "Okay.” Sadako was rather relieved. Supper times were always uneasy when her father was visiting from San Francisco, where he worked as a gardener for a well-to-do family (it was the same job he had held before the war). She tried her best to keep a pleasant digestible conversation going, but she always ended up tensely, delivering an overly ebullient monologue. Which word best describes Mr. Endo’s tone?
