Hi, everyone. I'm working on my first project for publication intent, and I need some advice on the behavior of one of the major supporting characters. I don't want to get overly in-depth with my question, but here is some necessary info. This single man is in his forties and has never lived with children. Thus, he should have an uncomfortable, maybe nervous reaction toward the protagonist: an eleven-year-old girl who falls into his custody. I personally have spent my entire life around kids and am not sure how to approach this situation. A few details have come to me, such as when the two characters first meet, it is clear to the reader that he has rehearsed what to say ahead of time. But, I could use advice on gestures or behavior or dialogue with this character. It should also be mentioned that the strange way he behaves needs to lead the protagonist to distrust him—although he has no bad intentions—then the development of the story brings them closer together, and he is less awkward toward the end. I hope this question isn't too complicated, and I would really appreciate feedback. Thank you! Taika.
