even super-geniuses don't actually talk like you do in this book. It's like you are doing it on purpose to aggravate Claudia, and stop that because don't be mean to your sister even if she is being a monumental bitch to you!

That actually struck me as pretty realistic for sisters that age, though. And it's sort of nice that even though Janine is smart, she's not necessarily mature because she's very much still fifteen.
