Otherwise, A nuclear family is a modern family, where has just 1 or 2 generations living together, so that every member all has their own space to do something, it will be very peaceful. More over in there, there are few people, so they will have more chances to take care each others because they can not let any others do that. May be sometime, We feel lonely to live in a nuclear family, but I think that time is a meaningful time for us to realize, to understand the value of the family more and it will be happier and happier when we respect every minute to live with family.
All in all, Living in a nuclear family is better, so that I prefer nuclear family to extended family.
