My 14 year old daughter asked me the other day if she could go and meet a friend who is a friend of a another girl who we know and who has been to our house several times and who I would trust. This "original" friend has introduced my daughter to her other friends on social media and now one of them has invited my daughter to go with her to the "gathering" of another friend of hers for his birthday. I don't know this girl (the inviter) apart from her name and that she is a friend of this "original" friend, who won't be going. My daughter would be going to meet this girl who invited her, and they would be going across London to another house where there is this birthday gathering, during the day, on Sunday, and I just feel it's a bit too much of the unknown for me. I feel if she is to go I would need to have contact with the inviter's parent, to make sure they are really going where they say, and the parent of the boy whose birthday it is, just to confirm that this is really what's happening. Even then, my gut feeling is it's not okay, so I'm just asking what people think. I have posted before in different threads about letting my daughter (then 13) out on her own, and we have started on this long and tricky road, but it's a constant worry for me, and I'm not handling it well. We have to work it out, and I have to be able to let her go to different places and at different times etc. but each time there's a new situation that comes up I have no parameters for dealing with it. And she is very good at picking up when I don't have in her view reasonable arguments against her going.
