If that happens, it will be a miracle.
I teach my students tha a real apology consists of these parts, and in the stated order:
1) A complete and truthful confession of the event(s) in question.
2) A declaration of responsibility for the actions, without any subjunctive clauses.
3) A sincere expression of regret.
4) A request for forgiveness.
5) An offer of restitution, which should not be offerred as a reward for being forgiven.
At no time should the person offer an excuse, or provide circumstances that would mitigate the offense. The apology must fit the offense, without placing any blame on the victim.
Such as:
"I harrassed you and threatened you. It was my choice to do so, and I claim sole responsibility for my actions. I am sorry for what I did to you, and I truly regret it. Please forgive me."
Then, no matter what the offended party says:
"Please accept my offer of ________. I know this won't change what happened, but I offer it in good faith."
How long can you hold your breath?
