What to say in a dialogue where u bump into your primary bully?

Person A: Oh, hey there. Fancy running into you.

Person B (primary bully): Well, well, well. Look who it is. What a surprise.

Person A: Yeah, it's been a while. How have you been?

Person B: Oh, you know, same old, same old. Just doing my thing.

Person A: That's good to hear. Listen, I wanted to talk to you about something.

Person B: Oh really? What could you possibly have to say to me?

Person A: I just wanted to let you know that the way you treated me in the past really affected me. It wasn't easy dealing with your constant bullying.

Person B: (pauses) Look, I... I didn't realize the impact I had on you. I guess I was just caught up in my own issues.

Person A: Well, it's never too late to acknowledge the impact of our actions. I hope you've grown since then.

Person B: Yeah, I have. I've learned a lot about empathy and understanding. I'm genuinely sorry for what I put you through.

Person A: Thank you for saying that. It means a lot to me. I've also grown and moved on from those difficult times.

Person B: I'm glad to hear that. I hope we can both leave the past behind and move forward.

Person A: Agreed. Let's focus on being better people and treating others with kindness.

Person B: Absolutely. I'll make sure to do my part.
