What are some major events in Black Like Me by John Howard Griffin?

In Black Like Me, major events are things that drive the plot and Griffin's character development.
The most important event is Griffin's decision to change his skin color. It's an exhausting process but it allows him to live as a person of a different race. This is the impetus for everything else that happens in the book; it allows him to see what life is like from another perspective.
Another important event is when Griffin decides that he's ready to be white again. His time living as a black man changed him. He realizes that when he's white, white people respect him and black people seem wary. When he's black, black people respect him and white people are cruel. This makes it difficult for him to come to terms with the way people are treated and treat each other.
Another important event is when Griffin faces a white bully while he appears to be a black man. The boy follows him down the street and says he's going to get him. Only when Griffin fights back does the boy finally go away. People don't seem interested in helping when he appeals to a couple for assistance.
Traveling with Rutledge is also an important event. Because Rutledge is white while Griffin is presenting as black, the differences between the facilities they can use is staggering. It's difficult for Griffin to find bathrooms, water fountains, or businesses that will accept him.
