Notice that when Ruth refers to Barack as “the other Obama son,” she essentially ignores the Old Man’s other four sons (Roy, Abo, Bernard, and little George), in addition to ignoring Auma. By ignoring them, she makes it clear that she, like Sarah, sees few of the Old Man’s children as legitimate and worthy of attention or any of the estate. But in realizing that Ruth isn’t yet over the Old Man, Barack also sees that this is far more complicated than he initially thought. Everyone in the family is, in their own way, still grieving the Old Man’s loss, and that seems to be coming out in exclusionary practices.
