Describe salva as a student, his school and what he learns

Eleven-year-old Salva sits perfectly, ostensibly paying attention to the teacher but dreaming about when he can get out on the road home. At home, he speaks Dinka, but here at school, his teacher teaches them Arabic. Salva knows he is lucky to be at school, though he cannot attend during the dry season because his family moves away from their village. Salva’s father is successful, owning many cattle and working as a judge. Salva has three brothers and two sisters.
