Ok, here's the story.
There is a girl I used to be with long time ago. When we split up, we still maintained good relationship.
We both live in a small town and bump into each other quite often. She's now dating another guy and he's very jealous. Every time we meet and she is with him, we start chatting and he's watching us for like 2 minutes with the most jealous and prejudice look I've ever seen so far.
Last time he interrupted us, took her by the hand, said 'We are in a hurry' and stormed off.
That kind of behaviour pissed me off a bit. It's not that I am into her, I just wanted to have a pleasant chat with my friend and it was obvious that she was into it as well.
I wanted to tell this jackass something, that would make him look a bit ridiculous yet would not come as some exposed offense.
Please, don't judge me, just thought some of you might come up with something clever to say in this sort of situation. Thanks!
