OP - sorry I don't think a movie will help!
We had friends for lunch the other day and one dad who has a 12 year old daughter was talking about his shock at some of her Instagram posts, etc and he was also saying that most of his DD's friends already have boyfriends. DH said, "Is this the age I need to get the shotgun then?"
It's not the first time he has made this sort of comment. We have 2 girls (eldest 9) and 3 boys, 2 of which are early teens, but he has never made any such comments about the boys. He has also said things like, "Any boy who wants to take DD out will have to get through me first" - half joking, but in full earshot of his daughters. He has told DS1 to "look out" for and look after for his sisters when they are older. He is British, but has a Middle Eastern background which I think influences him in this area, though not in any other.
The thing is, I've told him countless times that he's being unreasonable about this kind of thing and he does accept that he is, but also says he can't pretend that that's not how he feels and if I was in his shoes these days etc etc I would understand.
On the other hand, he's totally committed to his daughters' education and so on. I can only hope that when the time comes, the reality of having teenage daughters will be the thing that forces him to change his mindset.
