the thesis statement

I think the thesis statement of this book is sort of live and let live because Billie Jo talks about and i quote(page 128) "but if i played right enough maybe they would see past my hands. Maybe they could feel at ease with me again, and maybe then,I could feel at ease with myself." this quote proves how she takes on the blame for her father and blames her self for what happened.So then we move on through the book even more when she comes to realize that she is not responsible for what happened and that her father is to blame and sort of at the same time she forgives him and herself and is realizing that.(page 206)this quote proves it"As we walk together, side by side ,in the swell of the dust ,I am forgiving him,step by step,for the pail of kerosene.As we walk together,side by side,in the sole-deep dust,I am forgiving myself for all the rest"
So in my opinion Billie Jo is finally accepting that she can't control every thing that happens and that she should mourn over her mother but not take on the weight of her as guilt and bringing that back to my main point (live and let live is the thesis statement)her mother died but she shouldn't carry that around for her whole life (her hands being a silent reminder )and in the end she drops the weight of her guilt which proves my let live part of it (can't carry around guilt forever and if you did it would suck)so what do you think Give me your Ideas and thoughts.

Right now I'm going to talk about page 70 to 72 where its just after Billie Jo's Mum (Polly) dies and her aunt comes and all of the neighbours come to mourn and they talk about what had happened and the only thing Billie Jo hears them say is "Billie Jo threw the pail of kerosene".this kind of brings on the element of guilt within her father and Billie Jo  through the whole story .I think that this is a turning point in her life .What do you think?
