Yosef’s first question, after revealing his identity to his startled brothers is: “Is my father alive?” But had he not already been told that his father was not only alive, but worried sick about Yosef’s sole remaining full brother, Benyamin? Had Yehuda not related a whole conversation between the brothers and Yaakov, their father? And had the brothers not already told him about their aged father waiting at home? Why would Yosef ask: “Is my father alive” after all this?
