It's a hard lesson as a kid to learn how to not just do what everyone else wants you to do just to 'fit in'. And not learning to stand up for herself and her friend. All you can do is tell her you are disappointed in her choice and the reasons why. Some day in the future she may be in the same place as this friend she's turned away from and when that happens she'll be hurt and have this experience to look back on. But her friend..won't be there. Isn't tween life a pain?

Good Luck
