I wouldn't say she's sensitive, but sometimes over-dramatic. Even the slightest of problems would make her rage. The only time I see her normal is when she watches anime, like Gintama for example.
I'm not sure she has a strong mindset, but I believe she is independent to look after herself. But I feel she needs to improve the way she talks to people since the way she speaks to everyone differs. Most of the time when I hear here talk it sounds pretty rude unless you are to 'terms' with her.
When she goes out, at times she would dress inappropriately (in my opinion but since she is with her friends, I'd always think she'd be fine when she comes back home).If my sister's friends aren't here and my mother sees the way my sister dresses before she goes out, she doesn't let her and they get into a huge argument, to the point when I'd have to step in between the two and try to convince her to change. At this point, she thinks I side with my mother and then just puts on headphones, her shoes and heads out. When her friends are here, my mother trusts them enough to bring her back home safely but she still dislikes the way my sister dresses regardless.
I feel that the relationship between a mother and daughter are either really close or just unstable where external sources such as friends are the only way for bonds to improve.
I'm saddened to hear that the relationship between you (Decal and Unown) and your fathers aren't that great. I'd always assume that the father and son relationship would be the closest in a family. Guess I was lucky to be born with such a dad.
