What does the narrator clain will make pearl normal? Ch16.

The Narrator claims that the experience of grief will make pearl more like other children..... more normal.

There was no other attribute that so much impressed her with a sense of new and untransmitted vigour in Pearl's nature, as this never failing vivacity of spirits: she had not the disease of sadness, which almost all children, in these latter days, inherit, with the scrofula, from the troubles of their ancestors. Perhaps this, too, was a disease, and but the reflex of the wild energy with which Hester had fought against her sorrows before Pearl's birth. It was certainly a doubtful charm, imparting a hard, metallic lustre to the child's character. She wanted--what some people want throughout life--a grief that should deeply touch her, and thus humanise and make her capable of sympathy.
