Roll of Thunder, Hear My Cry

Cassie and her family visits Vicksburg which is like a market to buy everything. Then she bumps into Lilian Jean who is very rude to her. She resists to apologize but Lilian's father comes out and her grandma orders her to do so. she does it while feeling humilated."No day in all my life had ever been as cruel as this one" (116). When I first read this I don't understand why this Cassie doesn't understand about racism thing but now I assume that she has humiliated officially that day because of racism. She always doesn't like the idea of black being lower status than white. I think it is because Cassie doesn't know about racism. She is raised among blacks so she may not be aware of it. Maybe she just thinks that the fact that whites always get good is just unfair, nothing less, nothing more. But now she knows it and I'm sure she will have revenge to beat nasty white fellows.
