Why didn’t the sparrows take any notice of the bread crumbs thrown to them? How would you explain their strange behaviour at the death of the grandmother?
The sparrows expressed their grief at the death of the grandmother. They sat around her dead-body mourning her death. They didn’t chirrup. Nor did they touch the bread crumbs thrown to them by the narrator’s mother. They flew away quietly when the dead body was carried off. In this way, they paid their silent homage to the old lady.
