My ds best friend (they’re both 9) has recently started playing 18 games like Call of Duty, GTA. His parent are the ‘cool’ type and have no problem with this, they’ve bought the games for him… however I do have a problem with my 9yo playing them at his house, as I don’t believe he has the maturity or understanding - he’s a child. Friend’s mum makes out I’m being overprotective (in earshot of my ds) and my ds is annoyed and embarrassed that I won’t let him play those games… AIBU or is she?
