Bests & Worsts Reviews from Amazon

My 7yr. old daughters received this as a present and within the first few pages I was ready to put it down. Words like dumb, booger head, boring, tightwad are all used within the first chapters. And worst of all their used by the main character and child Bean. When Bean's Mother encourages her to play with their neighbor she calls her boring and states I told you I just don't want to. What does the mother do, she dismisses this behavior and says have it your way. All of these words and this interaction made it clear that I could not have my nice and sweet girls read this. I'm surprised by all the positive ratings. Have they all read the book? Even if the characters decide to change their ways the language alone is not one I want my daughters to mimic.
