It's good to protect and support her, but you also have to ensure she grows up with the correct morals. This might mean that you have to take a firmer hand when dealing with her as compared to before where you were friends.

If you were friends this might not be so, but as her father, you now have the right to reprimand and correct her as you see fit. Indeed, it is your responsibility to step in the moment you sense something is amiss, even if she is unhappy about it.

Being a father sometimes means having causing unhappiness to your child if it's for their own good. You can't let yourself feel down if Miss Elize is cross with you for disciplining her.
