Don't know if I'm being overprotective! DD, 13, has been invited to a party by a girl she claims is 'one of her best friends' but in reality she has been shopping with once. I haven're met the girl and she doesn't go to DD's school. I insisted DD showed me the Facebook invite, transpires it is a house party and around 200 kids seen to have been invited. No clue on supervision from adults and no way to find out. Invite also says 'bring your own drink' which could be innocuous...but then again. We are leaning heavily towards 'm way' cue one very unhappy teen which I can't bear. Opinions please?
