You must make her pay for it, regardless who it is, it was her fault, what if it had been a child she had hit instead of your car, she needs to be made aware of her mistake so she will have her wits about her at all times in future, I know she is a hot chick but that's no reason for you to have to pay for her mistake, if you let her off more the fool you, as I said before what if it had been your daughter, son, anyone for that matter?.
