Abstract: Chapter 4 tells stories of mischievous, naughty and fierce boys and girls, prompting us to rethink gendered moralities and how they are learned in childhood. Systematic behavioral analyses reveal gendered patterns in children’s moral experience, for example, boys initiate physical aggression, dominance and swearing more than girls, but girls assert themselves in more subtle ways, such as through tattling and scolding. I further explore how children’s learning of authority, aggression, boyhood, and violence is shaped by their family life as well as the larger historical trends. The chapter also examines how young girls understand their own situations and defend themselves. Despite the entrenched son-preference in this community, little girls are far from passive or submissive. To honor Arthur Wolf’s legacy on marriage and adoption and offer new insights on young girls’ emotional experience, which was not addressed in Wolf’s previous works, I present the case of an adopted daughter: an “unruly” girl who defies parental commands, asserts her own will, and negotiates love-hate relationships with different family members.
