Sarab and her brother Sateesh have been sharing household chores for several years. Recently, Sarab noticed that Sateesh consistently gets lighter tasks, such as taking out the trash, while she is assigned more time-consuming duties, like cooking and cleaning the entire house. When Sarab brought this up to their parents, they explained that Sateesh is assigned tasks based on his school workload and extracurricular activities, which are more demanding than Sarab’s. Sarab believes she is being treated unfairly and that the division of chores is biased.
