My 14 and a half year old ds has started meeting up with some of his school friends and has mentioned some girls that are also meeting up with them that go to another school. I'm trying to come across as 'cool' about this and not asking too much as he gets a bit embarrassed but I do feel a bit uncomfortable about him hanging out with people I know absolutely nothing about! I have said to him he can bring them home anytime, but at the moment they are meeting up once a week or so at the nearest town where they all go to school (we live in a village). He is my PFB and no trouble at the moment, but this is all new to me! What's the best way to proceed?
