A: Hey, B.
B: Hey, A. What's up?
A: Listen, I really want to say sorry.
B: Sorry? Say sorry for what?
A: For what I've done to you yesterday. I didn't mean to make you fall.
B: Oh, I see. It's okay! It was my fault either.
A: So you forgive me?
B: Of course. It wasn't your fault.
A: Thanks, B.
B: You're welcome, A.
