As I Lay Dying Questions 1-3

1. What does Jewel mean by "One lick less" on pages 14-15? How does it tie into the rest of the story?
2. How does the Bundren family home sit atop a "mountain" and next to a road? Are these different accounts meant to show the unreliableness of the narrators?
3. Is Bundren supposed to sound like burden? If so, does this connect to the 'curse'/burdens of the House of Atreus?
