] To be an American is to receive a continuing education on

] when increasingly large gestures of commitment are
] required (the engagement would come five months later),
] and he was taken in on a probationary basis. He proved to
] be sweet-tempered, if excitable, goofy and energetic,
] easily house-trained. In balance, a lot of fun. There's
] just one problem: Percy is a racist.
