I hope he does talk to her about manners and discipline. She's going to rebel more and more and he will have to stop her.
That will be great to watch. Does she respect his authority or not? Just like the time when she said she'd leave the house in response to his comments about discipline at home, I feel she will either talk back to him or refuse to follow his discipline.
HS will never hit her so I am dying to see what creative way he comes up with in order to either discipline her or get her to understand his point. And he is super smart - he doesn't yell at her in front of her grandparents this time, does he?
Nope! That's why he said he wanted to talk to her in private.
