One Option
It turned out that because of Hannah’s burns, they couldn’t treat her head with the medicine needed to kill the lice. They’d have to wait for her head to heal first. To do anything else would risk more harm. Therefore there was only one option, and that was for Hannah to just live with the lice. Hannah was upset, but more than anything, she wanted justice. She wanted the boy who did this to pay.
Anger
After a while, when her skin had healed more, Hannah went back to the hairstylist. She wanted to dye her hair red, because she liked the color, but also because she wanted to represent the fury she felt about the whole situation. She was planning to get justice, and that justice would involve the bullying getting his comeuppance. It wouldn’t be easy, but she had been shown kindness by the town, and they supported her.
