But Somehow It Sounds So Civilized

Sarah recently read The Indian in the Cupboard. She enjoyed it, so I picked it up and started reading. A few pages in...

Me: Sarah, did you understand this book? There are a lot of unusual words in here.
S: Yeah, I understood it.
Me: But it's British English. Did you understand all of that?
S, in fake British accent: Yes, and I'd like some tea.
Me: Oh, OK, so you get it?
Charlie: And she did start saying, "I'll bash you in straight!"
