It doesn’t matter if your family is a nuclear, extended or single-parent; it should be happy.
All families have many problems but the point of the family is that all the members together can solve them. If you fight with your family you know that in the end, all will be as first.
A perfect family doesn’t exist. But some characteristics a good family should have are:
1) help each other
2) listen to what each other says.
3) share the problems
4) show love and affection to each other.
5) argue but makeup afterwards.
So don’t worry about your family, because according to my opinion all families are good with different ways!!
