DD is in year 8 so they're all 12/13 years old. She's got a nice little group of friends about 6 of them in total. They've arranged to meet in town over the weekend. Just chatting about who's going and there's 1 girl who hasn't been included. Should I ask her to invite her or not get involved? She hasn't organised this herself, its just be arranged casually in school. DH thinks I shouldn't get involved in her social life but I don't like the thought of 1 child missing out. I'm not sure why she's not been asked.
