Tweens?

OK. I have heard this term a whole lot lately and I think more because of people like Miley Cyrus than anything. That age group is hugely popular right now. TV shows and singers target them. (think Jonas Brothers, Miley Cyrus, Ashely Tisdale...kill me now) I am raising four, count them FOUR daughters. Yes I am slightly insane. Anyway my twelve year old has me at my wits end right now. I realize young girls are pretty much selfish "woe is me, everyone hates me, I'm gonna run away" types of people but wow has the reality set in. My girls are really for the most part very good kids. I can't seem to get through to my twelve year old right now. She does not hear other people's opinions but only thinks we are trying to be mean to her. I need to make it through this but I only start to get the courage and then realize I have to do it still three more times. I think I may just have to find the Calgon, a bottle of White Zinfandel, a few candles and an empty house!!!
