With regard to the article “Saudi Arabia on track to produce technologically ahead sustainable cities” (Feb. 26), no matter how far we look into the future, a city is all about people, human beings, happy families and little children growing up healthy. A modest comfortable home is all that a family needs. At the same time the rich are entitled to the choice of the homes they can afford. The point to be understood is that every house is not a home. The laws of life make it clear that a house becomes a home only by the efforts of the ladies of the house. Muhammad Sarmad Alamgir Dar, Online response
