The way that Michael describes April (using the derogatory term for prostitute) shows even more clearly how set April’s reputation is. People think of her only in terms of her promiscuity. But to Claudia, April is more than her sex life—she’s Monday’s big sister. She, unlike seemingly everyone else, sees April as a full person. When Michael reveals why he always said Claudia was a church friend, it shows that he’s in tune with Claudia’s preferences—he knows how intent she is on avoiding rumors.
