Why was Carly offered a ride in John Bartons car and not Josie?

What chapter is this in?

I don't have my book with me, but I can tell you that John (school superstar) and Carly (model/ wealthy) move in the same socila circle at school. Carly and Josie don't get along...... this might be the reason that Josie isn't offered a ride and Carly is......

social circle.......... sorry, I need to spell check before I hit submit!
