My daughter is ridiculously well behaved, I am embarrassed to say that I am one of THOSE mum's who never have any trouble with her. Until today. The school called to say she had taken a lighter to school and did I want to go and collect it. I am horrified and embarrassed but more importantly I have absolutely no idea how to approach the subject once she returns from school. I don't want to come down too hard on her as this is completely out of character for her but I don't want to be too lenient and she thinks this is okay. What do I do??
