Siblings and Cousins
Own generation kin are treated quite differently according to sex. There is often a good deal of interaction among same sex, same generation kin, although it is my impression that sisters, sisters' daughters, and similarly related women are more likely to spend a great deal of time together than comparably related men.
Still, in many families, brothers are together a good deal before they marry. The elder serves as a mentor for the younger, and the younger helps the elder in whatever tasks the latter may be involved in. With marriage and the beginning of their own families, relations become more formal and distant, and sometimes competitiveness, even mutual hostility, emerges.
Relations between sisters are frequently close and warm in childhood when they are almost constantly together as a consequence of the isolation of women, which led—and, to a slightly lesser extent, still leads—to girls and young women spending much of their time in their own house and those of female relatives and neighbors whom they visit with their mother. After marriage, relations between sisters generally remain quite positive and lack the competitiveness that sometimes is seen between brothers.
Brothers and sisters are together less as children than are same sex siblings, since while the girls stay in the home when they are not in school, the boys, after the age of seven or eight, are either in school or wandering the neighborhood and playing games with other boys. There is some conflict between brothers and sisters deriving from brothers attempting to control their sisters, especially with regard to the sisters being allowed to go out of the house. Sisters often depend on their brothers to do errands for them which involve going outside, and brothers depend on their sisters for part of the cooking, cleaning, and mending they require. As might be expected, this
work for brothers by sisters sometimes leads to resentment, but it also serves as a check on brothers' attempts to control their sisters' activities.
