Two weeks before Passover, Helen, an observant Jew, begins ridding her house of all traces of chometz, or leavening. Every crumb has been removed for the eight-day festival commemorating the exodus of Jews from Egypt and the Passover Seder, or ritual meal, to which she has invited Natalie, a non-religious cousin.
When Natalie arrives, she hands her hostess a cake. Dismayed, Helen scolds, "How could you have brought a cake into this house after I worked so hard getting rid of the chometz? "
