NC because I think at treats one of them is a mnetter 
Waiting in the playground for the kids to come out of school today with dh.
My good friend is in a happy relationship and can be a lighthearted cheeky flirt. One of her friends (another dad) walks by quickly and pinches her bum, she laughs and and sticks her two fingers up at him. This is how they are and it's harmless. Both in happy relationships and just very jokey. There's nothing covert or hidden about it. It's a running joke if we all go to the pub together.
Anyway Dh is shocked and keeps bringing it up saying that if someone tried that on me they'd be loosing some teeth. I tried to explain it's just a jokey wind up thing and that he doesn't get it.
