Mom and Fumi are on their way home from having lunch near the train station when Fumi's stomach starts to hurt. Telling her to hold it until they get home, Mom talks about her childhood experience of urgently needing a toilet. While watching "Cinderella", Bunji hits Fumi with simple questions. Fumi's answers are curt. Unconvinced, Bunji extends the topic to a picture book of "Momotaro"... Bunji says he will take his bath by himself. Thinking that maybe he is growing up a little, Mom is impressed, but it seems he isn't warming himself properly. Wondering why, she peeks into the bath one day... Having rushed out to bring in the laundry after a sudden shower, Mom blows her top at Dad, Bunji, and Fumi when they won't help her at all.
