“Cry about the simple hell people give other people – without even thinking. Cry about the hell white people give colored folks, without even stopping to think that they’re people, too.”
– Harper Lee
To Kill a Mockingbird, Chapter 20. Dolphus Raymond is predicting that Dill won’t cry about these things when he gets older. Once Scout and Dill get accustomed to the world as it is, they will no longer be shocked by the prejudices and injustices they witness. To Dolphus, it seems children have more moral outrage than adults.
