What does Atticus tell Jem after the verdict when he's crying?

Jem is crying and angry - he thought that the case was clearly in Tom's favor. Atticus is exhausted and when Jem asks him how the jury could have done it he responds, "I don't know, but they did it. They've done it before and they did it tonight and they'll do it again and when they do it - seems like only children weep." However, the next morning, he explains that there's a good possibility for the case to be appealed in a higher court.
