In India, you do not call your elder sibling by their first name alone. It is Bhaiya (brother), Didi (sister), Chachaji (uncle). This linguistic respect maintains order. Grandparents are not sent to "homes"; they are the CEOs of the household emotions.

To read about the Indian family lifestyle is to understand a philosophy: Vasudhaiva Kutumbakam —the world is one family. This is practiced on a micro scale first.
