Answer: Gideon knows that Teddy will soon be grown and become a "master" just like the other whites
Explanation:
“No Witchcraft for Sale,” by Doris Lessing, is the story of a black servant cook, Gideon, his employers, a white South African couple, and their son, Teddy. Although They all seem to have a nice relationship, and Teddy becomes good friends with Teddy, the racial tension grows throughout the story, and Gideon realizes that his employers and even the little boiy are prejudice towards him because of the color of his skin and his cultural background. When, by the end of the story, Gideon tells Teddy that he´ll grow up to have a farm of his own, although it seems like a loving comment, it shows that Gideon has understood that Teddy will become like his parents.
