Go with your gut instincts..the bittersweet emotions of your dear baby girl growing up (some teens don't like to hear that), but I know its hard! But all I have to share is this: when I was about that age, I never told my Parents about any "date" I had.
So, I would tell my parents I was going to the movies with my 'girlfriends' and then they would drive me there and drop me off.
Then me, my girlfriends and the "guy" would then pair up, on our 'date.' It was all innocent...
I know that when a child asks her/his parents for permission to "date" it is not only about going out with the girl/boy, they are also asking, "do you trust me? I will not give you advice as I do not know your family, your values, nor do I understand your relationship with your daughter.
I know that the more parents try to keep their children young, the more their friends may pressure them to grow up. I know that you are in a position to open the communication for ALL her dating experiences.
but I guess I never felt real comfortable telling my parents.
