Life Lessons

In the book, To Kill a Mockingbird, Jem and Scout are growing up and as the books starts to close they are learning some life lessons from the adults around them. A life less on that Scout learns is that not everyone has the same feelings like Atticus does about blacks and racism and everyone being equal. Neither Scout or Jem liked how Mr. Ewell and Mayella didn't have to go to jail and Tom Robinson had to go even though he wasn't guilty. Also, how Mr. Ewell treats Atticus after the trial, how he spits in Atticus's face and calls him names about how he defended a black man. In the beginning of the book Scout doesn't realize that there is a different world out there and now that she's seen what other people think she's starting to realize that.
When Atticus gets home from the town he tells Jem and Scout "I destroyed his last shred of credibility at that trial, if he had any to begin with." Attcuis is saying that even though he didn't go to court he still was very angry at Atticus to make the jury think that maybe Bob Ewell should go to jail. But since Tom Robinson was a black man Bob Ewell didn't go to jail even though he should have.
