I actually think Britt seems to have a rather messy home life. How can we expect a 12 year old in a seemingly strange household to act like a 25 year old? Maybe she has genuine reasons to fear her mother. I've seen other posts where she has expressed this.

I guess I don't mind a 12 year old acting like a 12 year old nearly as much as I mind 15 year olds saying things like "kids these days" (as though they know any other days) or trying extra hard to appear mature.

She's a kid, let's back off.
