person A: I got into a fight with my brother this weekend. I said some things I shouldn't have said. 
person B: if you regret what you did you should go apologise for you said to him!
person A: I did apologize but I still can't shake the feeling that I went too far. I'm not proud of how I acted at all. 
person B: i hope he can forgive you and help you forget about what you said.
