A man comes home at the evening after the work. His wife meets him, kisses him. The man is surprised with a such sudden change. He sits at a table in kitchen, but the wife informs him: "Honey, our ratios transfer to the market ratios. Supper costs $5." The husband has estimated and decided it isn't too expensive. He has agreed. The wife lays the table. The husband pays off. After the supper he gives a shirt to her and says: "Wash it, please." "It costs $3" the wife answers. The husband pays $3 to her. The wife washes. The time for going to bed. The man touches his wife, but she says: "It costs $10." "But I have only $7 left" the husband responds, turns back and asleep. The man wakes up at the night because of the noise. He sees a light in all rooms. His wife looking for something in a handbag. He asks her: "What are you looking for?" "I am looking for $3 to lend you."
