Rosa Priore, like every Saturday, prepares the ragù for Sunday. Her husband Peppino wanders nervously in the kitchen, arguing with her about every little thing. The reason for the nervousness manifests itself the next day. Is Sunday. The entire Priore family is gathered in front of the ragù. Rosa wore the blue scarf given to her by the neighbor, the very thoughtful accountant Ianniello. Peppino does not touch food and, to the umpteenth compliment addressed by the accountant to the cook, accuses them both in no uncertain terms of having a "lousy affair".
