In Korea given the cost of housing its common for adult children to live with their parents until they are married. Even then my wife wouldn't move more 10km away from her mothers house. Its great when it comes to child care for our 2 small children, but I don't understand this eternal dependance on parents. I left home when I graduated high school and never looked back. My parents supported my tuition fees through college but made it clear that after that I was on my own.
