You were walking with your friend outside and just talked, when you wanted to say something, he stopped you, pointing somewhere

"Hey didn‘t you and that guy there date before?“

You looked over and saw your ex, crowded by people. He noticed you, having a smirk in his face while showing the middle finger to you

You did the same, pointing it to him while remembering old days together with him

You got a little sad, but throwing it off and turning to your friend, continuing to walk

"Yeah, we did.“
