At the beginning of Chapter 23, Atticus is approached and threatened at the post office by Bob Ewell. Bob Ewell even spits into Atticus's face and tries to fight him. However, Atticus remains calm and refuses to retailate. Atticus simply walks away and does not believe that Bob Ewell will follow through with any of his threats. Despite the feelings of Alexandra and his children, Atticus believes that Bob Ewell has taken his anger out on him that day at the post office. Atticus does not think Bob Ewell is capable of harming his family and dismisses his threats. In my opinion, Atticus should have at least notified Sheriff Tate of the incident. Atticus is correct in viewing Bob Ewell as a coward, but he is rather naive to believe that Bob will not hold a grudge. I think that it would have been out of Atticus's character to have fought Bob Ewell, but he should have taken Bob's threats more serious and notified the authorities.
