Character appearance reference (MUST match exactly):
- Ольга Николаевна: 55 year old Russian woman, plump, rosy cheeks, wearing a floral housecoat (khalat) and a headscarf with curlers underneath. Commanding but loving expression.
- Клавдия Петровна: 60+ year old woman, postwoman, glasses on her forehead, carrying a shoulder bag over her jacket. Nosy expression.
