What are some quotes about Okonkwo being stubborn in Things Fall Apart?

[Okonkwo]: “An Umuofia man does not refuse a call,” he said. “He may refuse to do what he is asked; he does not refuse to be asked.” ch 23

“Answer me,” roared Okonkwo, “before I kill you!” He seized a heavy stick that lay on the dwarf wall and hit him two or three savage blows.

“Answer me!” he roared again. Nwoye stood looking at him and did not say a word. The women were screaming outside, afraid to go in. ch 17
