What is the main idea of bud, not buddy in chapter 11

Well, the car only goes thirty feet and then conks out. So much for that plan. The man comes up, knocks on the window and asks what is going on.Sticking up his little knife, Bud says that the man must be a vampire. The man is frustrated and tells Bud he cannot be a vampire because he had a sandwich and pop. And he has no fangs.Bud lets him back into the car but unlocks his side of the car in case the man pulls anything funny. They head toward Flint for the night.Trying to figure out what to do with Bud, the man asks him lots of questions about his family, and Bud tells him his father is Calloway. The man, Mr. Lewis, knows him. He is famous.While they drive along, Bud requests that Mr. Lewis let him finish his meal before he asks any more questions.Bud backwashes into his soda, and Mr. Lewis teases him about it. He is one funny guy. Actually, he is also a grandfather.
