Enders Game

Ender orients himself to the null gravity with a game, imagining that he is climbing down a wall and that the ship is hanging onto the bottom of the planet. Ender sees Graff, who turns out to be the principal of the school. Ender is glad to see Graff manipulating his sense of gravity, but when he smiles, Graff shouts at him to explain himself. Ender's good answer leads Graff to reply that Ender is the only boy on the launch with any brains, and this statement makes the other boys look stupid, so they naturally begin to hate him.
