@Papyta You forget it's historical fiction, so they have to pay dowry to marry, so he do have the right. The same way a father has the right to correct their children. She's lucky he didn't beat her for dismissing his warning.
She may not have lived in the noblest of society, but she lived until adulthood in both lives, and might even have read fictional novels like us. Would you, even without the general view, dismiss a warning about dangerous bandits in the area just because it might not happen to you?
Being from 21st Century would be more reason for her to be wary of those dangers as she knows how low humans can get, and if she's not childsh she wouldn't be petty about being grounded.
But disagreeing with her actions might just be because I grew up in a place and time where you have to be careful of even the people in our house, which it seems to not be the case for her, as she can be so careless to the point of almost seeing 2 of her servants dieing trying to protect her.
