In what ways is Charlie different from his fellow golden ticket finders?

For one thing, Charlie is accompanied by only one adult, while the other children have brought both of their parents instead. Charlie has brought his grandfather, Grandpa Joe, demonstrating a marked difference between his character and those of the other four winners. Another way in which Charlie differs from his fellow winners is that he is polite, quiet, kind, conscientious, and concerned about the welfare of others, while each of the other children is impolite, rude, demanding, greedy, and selfish.
