Interviewer: "If mud houses stay cool, and cement houses are hot and require air-conditioning, why do people build with cement instead of mud?"

Master mason: "If one has a lot of money and he wants many apartments, you cannot have 11 apartments in a mud house. In cement, you build a house of 7 floors or 5 floors, and each floor can have 4 apartments, and you can make money from it."
