Write a summary of Okonkwo's character in Things Fall Apart, including an explanation of how his interactions with other characters advance the themes of the novel. Provide details from the novel to support your response.

Okonkwo is a very strong and fierce man. Apart from that he is successful but the problem with him is that he does not want to express his softer side because he considers this to be weak. He disowns his son Nwoye for the simple reason that he reminds him of his father. He has a better relationship with his daughter Enzima who is tough like him. Had he been more honest with himself things would have turned out differently.
