Well, i belive that happiness is reach by a lot of factors, and clearly the family gets place in an important part of it, specially if your family are close. The bounds that you have with your mom, dad, brother and sisters is unbreakable and last for ever.
You always get mad, upset or fight, but your sister is always your sister -and of course the same with your brother-. In my case i´ve have two sisters and one brother, and no mather how mad i can get, they will always be my family, and that is unique.
Also you can include in the concept family more people than your nuclear family. I am talking about the extend family; grand parents, aunts and uncles, cuosins, nephews, and the list continues.
I have a really close extend family and i love it. We get together where ever we can, and we share everything.
