     In "The Rules of the Game", Waverly Jong is a gifted girl with skills in playing chess. When her brother gets a gift from church for Christmas, it is the first chess set Waverly has seen. She learned how to play and soon, she excelled into playing at the national level. When her mother began to show her off, Waverly got embarrassed and upset at her mother. She yelled at her in public telling her mother that if she wanted to show off something so badly, then her mother should play chess instead so she can brag. She then proceeds in running away. When she gets back home, her mother tells her family to ignore her. And says that if she did not care about her family, her family doesn't have to care about her.
