In Bunol, Spain, people pelt each other with tomatoes during a festival called Tomatina (inset). Chinese grandmothers and mothers would probably see red in this. As a child, I remember Mother reminding the children to finish their food so that there is not a grain of rice left on the plate. Finish your rice or Lei Gong will get you! Lei Gong (雷公) is the Thunder God in Chinese mythology. Chinese children are traditionally taught that if a person waste his food, thunder will strike him. It does not have to work that way, don't you think?
