DD16s best friend (lets call her C) met 2 boys (brothers, T16 and J17) on holiday this summer, apparently she had a little thing go on with the 17 year old so introduced DD to his brother through Facebook as he apparently thought she was really pretty and "could be a model" bless him so they could do a double date sort of situation.
DD and T have been talking pretty much non stop since July so him, his J and C have suggested they all meet up this weekend so they can actually meet face to face. They live in Reading and we live an hour and a half train journey away so most likely it'll be a sleepover. DD and C want to go to reading rather than they come here.
I'm really in 2 minds on whether to say she can or not. Whilst she's never met T they have FaceTimed a lot and C and her family have met them and their family so Cs mum is fine with them to go down and spend the night if they like. Apparently she has also spoken to the boys mum and they are all fine too. I feel like I'm in a different situation though as me and DD haven't yet met any of them and could meet them and decide she doesn't like them and then be stuck there.
I just need other parents opinions so I can get it all together in my head.
TIA :)
