I found chapter thirteen very interesting. They find a dead dog on the road. Their grandfather ends up dying as well.  They are not allowed to bury him for it is against the law. But, they end up doing it anyways with having the family and the preacher their. It is so depressing to read that they couldn't even bury him, let alone a proper funeral. It shows that without money you couldn't do anything. It is not only affecting the people but also the animals. As they are just running around everywhere, probably starving. Nobody can take care of them as people are trying to feed themselves.
       People are rushing from one place to another, running after money.The fat man talks about how people are going somewhere and they all got somewhere to go.My favorite passage is " I don' know what the country's comin' to," the fat man continued. His complaint had shifted now and he was no longer talking to or about the Joads. "Fifty-six cars a folks go by ever; day, folks all movin; west with kids an' househo' stuff. Where they goin'? what they gonna do?". I think the theme would be the country if falling apart without the money, that they are going to be end up like grandpa and the dog.
