This is Joshie. He's my little brother and he's adopted."" Also he's ""a pest"" like ""my sister"" who is not adopted. And, as seen in Hausherr's photos, he's notably darker-skinned than his blond sisters and mother. The problem isn't Joshie, though; it's Rodney next door, who tells ""us"" that ""Joshie can't be our real brother, not ever."" But when Joshie makes himself more of a pest than usual, Rodney recognizes the similarity to his own little brother; and just as the narrator has taught Rodney that there are lots of ways to make paper airplanes, she also convinces him at last that there are lots of ways to get brothers and sisters. Well contrived, with natural-looking photos--but you won't forget for a minute that it's all message.
