A happy family is made of many complicated things. But this things are not achieve by learning or working hard these things are achieve by just having a bonding with your family.
A happy family is compost of everyone in the family and love for each other. Even though a family is complete but love is not in the air, there family is not happy, and maybe it is full of misery and lack of attention from one other. Communication is also essential because without communication a family is not a family and there would be no bonding without it.
