Hannah?
I know many people can't stand her, I can't stand her either.
To me she comes across as a toddler acting like an adult. The way she walks around and presents herself to me is like a little toddler acting like an adult. Some of her actions and reactions are like that of a little kid also. Her hair cut it like that of a young child. Even her teeth look like a little kids teeth before the adult teeth came in. She acts out like a young kid for attention and to get her way.
Seriously look at the faces she makes and the way she acts when she tries to show emotion. I think it's her trying to look cute but it just seems so awkward and weirdly out of place.
I have a younger daughter and it's cute for a kid but not an adult.
