I'm sorry that I'm late.
I'm sorry for hurting your feelings.
Pardon me for cutting ahead.
Please forgive me for saying that.
I would like to apologize for my behavior.
Sorry, but I won't be able to make it to the party.
I'm sorry for stepping on your toes.
That was wrong of me to do.
That's all right.
I accept your apology.
It's okay.
Don't worry about it.
No need to apologize!
I'm the one that needs to apologize.
No harm done.
No problem.
I understand, it's okay.
Don't mention it.
No big deal.
It happens to the best of us.
