Don't know if I'm being paranoid/overprotective here.
Heard DD talking to someone in her room last night - no big deal as she's often online with friends.
Casually asked her before bed, who she'd been chatting to and she told me she's befriended another 15 yr old girl in ireland.
DD is a mega fangirl of a popstar and I know she's part of social media groups related to this person, so I think this is where this has probably grown from.
However, I went in at the deep end a little and told her I wasn't happy with her having face to face conversations with people she only knows online. DD relied that they have facetimed quite a bit and that she can physically see that this is a similar aged girl - not some creepy individual posing as someone younger.
I said we'd talk about it further today, but how would you feel about this? Is this the norm now for meeting people with similar interests? I know that the landscape of social interaction is completely different to what it was when I was 15, but something about it is bothering me and I need some perspective from other parents!
