A while back I had a coworker who just got back from a 3-month training in India. He was sharing his discoveries, his experiences with us. I still remember his face expression when he exclaimed : " most of my team members live with their parents!" It was something so unbelievable and so astonishing for him.
Then I had a chance to talk to an Indian coworker who came to France for a year assignment. She told me that it was the first time in her life she had to cook for herself, eat by herself and do everything by herself. Even when she went to University to further her studies, she was living with a bunch of friends. Her family would come to visit her whenever she missed them. Life was always surrounded by friends and family.
Coming from Malaysia and now living in France, I know where they are coming from. There is no right or wrong, simply a different preference in life. I wouldn't trade off my life living two years with 11 house-mates sharing a 3-bedroom apartment, but I don't know if I could accept living with my in laws, just like many do in Malaysia. When I was studying in France, I discovered that most of the students lived in a studio, a tiny space where everything is included in one spot : bedroom, living room, kitchen. There were many private studios to rent out to students, and in the University hostel, everyone has their own room/space/studio. That was something I had never seen in Malaysia. My University hostel in Malaysia was consisted of rooms with minimum two students. Most people who rented private property would prefer to share a room or an apartment to minimize the rental cost. The University provided tutorial classrooms and the libraries were opened till mid-night. So students had places to go if they wanted to study in a quiet environment.
My MIL told me that in the past, maybe around 40 - 50 years ago, French families used to stay under one roof too. However the society evolves, and French emphasis on their privacy. Who knows maybe in 50 years, the Indian or the Malaysian societies will go through the same path just like the French? That kids would want to leave their parents and build their nest as soon as they go for their higher education?
