What does Nadira say her father has taught her about morality in America in Section 6: Chapter 7?

It was good for Abba to marry someone who was not afraid since he believes in doing the right thing, and this is what he taught his daughters, though it was difficult to know what the right thing was after they came to America. Abba told them the most important thing was not to stick out, but Nadira believes it hurts him to hide so much.
