Absent for what reason?

Domu: Jarryd did not come to school today
Me: Maybe he's sick
Domu: No, he's not sick.
Me: Why do you think he didn't come to school today?
Domu: He's working
Me: What? He's too young to work.
Domu: No! He can work.
Me: But he's six years old.
Domu: Yes, but he can work. Before school he works. Yesterday he worked fast that's why he can go to school. Today he worked slow so he cannot go to school.
