Dr Jekyll and MRS. Hyde

I remember being sooo excited about having a baby girl...a princess...a shopping buddy....a cheerleader....however, lately I have had a rebellious, out of control, UFC fighter. That's right- UFC fighter! She has always been an independent, strong-willed, quick-witted little princess (diva is more like it) but on Tuesday she turned into MRS.HYDE.
I got to school to pick her up from the after-school program and the teacher said, "She has been in quite a bit of trouble today. Could you please sign this paper because if she continues she will no longer be allowed to participate in this program." Holy crap!!! I instantly felt my face get red and my mind was racing with all of the thoughts of what could have happened. I turned to Neely and asked what she did...she simply said, "I punched a girl in the face. She only bled for a minute." OMG!!!! I froze- What do you say? What do you do? My first reaction- what child and is she ok? 2nd reaction-How do I handle this? What is a reasonable punishment for Neely? I apologized to the teacher, walked Neely to the car, and counted to 10 about 20 times!!! We went straight to football practice from there so I didn't even get to talk to Rob until dinner about 7 pm that night. We made Neely recount the story in her words... basically the girl told Neely that she had make-up in her backpack, Neely asked to use some, the girl said she was just joking, Neely said don't lie to me and punched her in the face. Where is the nearest boarding school and what did I fail to do as a parent for her to think this is reasonable?! After a longgggg talk, many privileges revoked, and no TV she is starting to come around. The princess, fun-loving, baby girl has turned into a "mean girl". My worst nightmare!!! I want her to be a good person, good friend, one who will stand up for her friends, and do things right. Not the girl who everyone avoids making eye contact with and who thinks they can get what they want by pushing everyone else around. We have spent a lot of time together this last week talking about what being a "big girl" means, responsibilities, and expectations. I hope and pray that this is a one time occurrence because if not- we are seriously forking out some dough for boarding school!
