Roll of Thunder ,Hear My Cry Pg102-151

My summary:
It still describes that what happened to author. One day, their grandmother went to the market to sell something. These children followed their grandmother also. In this way, they can help their grandmother to sell. But something happened to author. When author walked to bring something to her grandmother, she bumped into Lillian Jean Simms. Then author apologize to him. But Lillian ordered her to get down in the road. But author refused it. Then her grand mother come here, and let author to get down in the road. Grandmother looks very sad. After this event, grandmother told their children that they are black, so they have to follow white men` s order. Then a man went to their house, he is their uncle. His name is Hammer. When he heard this event, he was taking a gun to kill Lillian. But he was refused by grandmother. She said that if you went there, you would be killed by them. We were weak. They were strong. Then Hammer followed grand mother` s order...
My response:
Since I read here, I have felt so sad about them. The author is teased by Lillian, but her grandmother just followed them to let Cassie get down in the road. Because they were black, white can do anything that they want for them. I think that the society system was not perfect in the old society. It was unfair to them. They can not do anything to protect themselves. So that is the reason that the black people need freedom to protect themselves. So I believed in next chapter that they can have hope for their freedom.
