In the story I'm writing, the character behaves differently when they're spending time with their mother - they are conflicted. They idolise their mother on the one hand, but as they have grown up (in dwarf years 45, in human years that'd be ~15-18) they realise their mother hasn't always been there as a parent and when she does fill that role, the mother is babying her daughter in a way she's finding frustrating and chafing.
I've looked at a few external articles covering finding your character's voice, as well as this very good Q&A post:
Finding the 'voice' of a character
However, because the way the character behaves is different with her mother, and how she is conflicted, I'm struggling to follow the advice from that post.
To over come this, I tried to do a bit of an exercise where it's just the two characters (mother and daughter) talking to each other, no other descriptions etc. The first character speaking is the mother, and it alternates to the main character and back every new line:
Hrafnhildur, your hair is a nightmare! It's difficult enough as it is... Is that dough? How did you get dough in your hair?
I was fighting orcs mamma! You know, the kind you used to fight?
Hmpph... I don't remember any orcs in my kitchen, anyway how does that explain the dough?
It got knocked... In the fight... I knocked it mamma. I was just trying to fight like you used to...?
Hmmm, I normally know you've been back in the kitchen by the trail of crumbs, not by dough that's been knocked over... but what did I say about moving things around?
Mama if you don't want me back in the kitchen, you can just say so!
Krummi, dearest, you now that's not true! I just haven't been free to ... Supervise you.... Fighting orcs.
I don't need supervising! It's a kitchen not a battlefield mama! There weren't really any orcs... I... Are you afraid I might take notes again?
Hrafn! You don't learn by taking notes with your hands! Use your eyes! Like you should have been doing in the kitchen when the dough for knocked over!
It feels to me a little stilted, at least to start. The character I'm trying to find the voice of is lying to soften the conflict between idolising her mother and being chafed. But the lies are too childish sounding if they're trying to act mature.
If she didn't idolise her mother she could have just replied something like:
I'm a grown dwarf mamma, so what I got dough in my hair. I can get it out myself! What I was doing in the kitchen was my own business!
If she didn't feel chafed:
Oh I'm so sorry mamma, I didn't mean to knock over the dough. I just wanted to get something to eat, so I can grow up to be a warrior like you were! Please let me back in the kitchen.
I do want the two to have a great and really close relationship when there's no other conflict (e.g. dough in hair) or certain topics aren't brought up (taking notes in the kitchen), and the chafing to be only when there's conflict. For instance, they play a sort of hide and seek together, which I want to imply is a long-standing sort of game they have.
How can I achieve a balance and find a voice for the character that communicates they're conflicted?
