Neighbor:
You're not watching the soldiers, Joseph? Joseph:
We've seen Romans before. Neighbor:
Yes. And we will see them again. [the neighbor examines some boards which have not been assembled] Neighbor:
My table is not finished. Where is your son? Joseph:
He's walking in the hills. Neighbor:
[disapproving]
Mm-hm. He neglects his work, Joseph. Joseph:
No. Once I reproached him with forgetting his work. He said to me, "I must be about my Father's business." Neighbor:
Then why isn't he here, working? Joseph:
[smiling]
