Those "kids" would not be welcome at my house and I agree that a bill should be sent for those items that are gone. We have a friend who sometimes brings his little grandson when he comes to visit. First time he did that and thought he could turn his grandson loose in our house, I nipped it in the bud straight off. No more problem. That brat might be his precious grandson but not ours. And you should not have to lock rooms in your own house, those kids should be learning respect of other people's property.
