Daisy, Daisy Adair genuflects before entering a church pew. As a Catholic neophyte, it makes sense that she doesn't know the direction of the Catholic sign of the cross as she almost kneels-- she crosses herself the way a Byzantine would. The second time she enters the pew, she crosses herself correctly. The third time, she doesn't genuflect at all.
