How does Sarah feel when the lamb dies? What does she do? Who comforts her?

Sarah is devastated by the death of the lamb. She cries for it, protects it, and shakes her fist at the carrion birds circling above. Nick comforts her.

She cried when we found a lamb that had died, and she shouted and shook her fist at the turkey buzzards that came from nowhere to eat it. She would not let Caleb or me come near. And that night, Papa went with a shovel to bury the sheep and a lantern to bring Sarah back. She sat on the porch alone. Nick crept up to lean against her knees.
