From these examples of interaction between parents and children and between husbands and wives we see behavioral practices compatible with the framework of this chapter. Cultures seem to have developed universally a variety of mechanisms for regulating interaction between strangers, acquaintances, in-laws, or family members. These mechanisms enable people to shut themselves off from others or to be accessible to others. Also, these privacy regulation mechanisms can operate in temporal simultaneity, as in the case of the Mehinacu husband and wife, or they can function over longer cyclical periods, as in the relationship between the mother, father, and child in the Kwama culture. And, to reiterate another theme, privacy is controlled by a variety of behavioral mechanisms that may be culturally unique and adapted to the particular Circumstances of a society.
