Atticus is quite courageous when Bob Ewell confronts him after the trial. In chapter 23, Bob Ewell spits in Atticus' face. When Atticus does not retaliate, Bob Ewell questions his courage by asking if Atticus is afraid to fight. Atticus responds by saying:
"No, too old." and walks off.
Jem and Atticus are talking later on about the incident with Bob Ewell spitting in Atticus' face. Atticus provides Jem with the reason he did not retaliate:
"Jem, see if you can stand in Bob Ewell's shoes a minute. I destroyed his last shred of credibility at that trial, if he had any to begin with. The man had to have some kind of comeback, his kind always does. So if spitting in my face and threatening me saved Mayella Ewell one extra beating, that's something I'll gladly take. He had to take it out on somebody and I'd rather it be me than that houseful of children out there."
Truly, Atticus acts courageously by walking away. He handles Bob Ewell's attack with courage. He does not fight Bob Ewell. He chooses to walk away without a fight. It takes real courage to walk away after someone spits in your face. Atticus is a great role model for his children. He even has a sense of humor about the whole incident. Atticus proves his sense of humor by saying:
"I wish Bob Ewell wouldn't chew tobacco."
Atticus has amazing self control. He proves to be courageous in the face of Bob Ewell's confrontation. Atticus' children learn so much about their father as he just walks away from a fight. It would have been easy to fight. It had to have been difficult to walk away from a man who spits in your face. Atticus has the courage of a real man.
