families are traditionally very large.Many generations can share the same house.Parents,young children,grandparents,aunts,and uncles all live together.This is called an "extended family." Everyone shares responsibility for taking care of the children,sick family members,and elderly relatives.Other countries have a "nuclear family" system.Hear,the parents and their children live together,and other relatives live separately.In this system,elderly relatives usually live on their own until they are too old to take care of themselves.Then,if no family members are able to care for them,they usually gi to a nursing home.Here,they receive the care they need,and their family visits them from time to time.
