I’m glad she hardened her heart and not just jumped at the chance of kindness her parents showed by forgiving them right away. But harboring resentments will not be healthy. Rather than getting angry and feeling pain, i think it’s better to act indifferent? Show them whatever they did have no effects on her, while showing a completely different side towards the people who cared abt her since the start. I think it will hurt her parents more than just hating them. A perfect revenge if you ask me.
