Lovely video: Why do we need sister at home?

A video has been posted on social media recently that shows an adorable girl child is saving its brother when their father was ‘slapping’ the big brother.
The relation between brother and sister is always wonderful. Many people say that the sister is the synonym of mother. After watching the video I am sure, you will rely on the statement.
This girl literally is quarrelling with father as she can not tolerate the father’s activities.
Siblings play a unique role in one another’s lives that simulates the companionship of parents as well as the influence and assistance of friends.
Because siblings often grow up in the same household, they have a large amount of exposure to one another, like other members of the immediate family.
However, though a sibling relationship can have both hierarchical and reciprocal elements, this relationship tends to be more egalitarian and symmetrical than with family members of other generations.
Furthermore, sibling relationships often reflect the overall condition of cohesiveness within a family.
