Dc1 has a friend over, both are 12. I overhear them debating whether to ask my permission and encourage them to do so: they want to play a 12-rated game in our living room.
My problem is that dc2 is 10 and dc3 is 6, they are already doing something in the living room and will definitely watch the 12 game.
So what do I say? I'm not happy with the answer I gave them (that it wd be better to play it at the friend's house) because I think I've sent the message that dc1 should do things outside the house that I would not permit at home. Or am I over-thinking it?
