Chapter: 5 Why is Salva upset about where they are walking to?

The next morning Marial and Salva begin walking together. Marial says they are walking East; Salva knows this, but asks where they are going. Marial says it must be Ethiopia. Marial can tell Salva is nervous about going too far because they want their families to find them, so he jokes that they’ll keep going East until they go in a circle and come home. Salva laughs.
