I say a fitting punishment would be to let her stew in this haircut for a few weeks. That way she will learn a lesson and you will have time to save up a few bucks for a trip to the "hair shop". I know it's frustrating, kids have such beautiful hair! But it's a girl thing. I totally cut my own hair when I was 12 and my parents were at the grocery store. Needless to say, it was awful!

Hang in there, sister.
