How do you respond to someone who is apologizing?

Answer 1

you either say you accept or you dont.

you either say you're sorry too, or not accept their apology.

When someone is really apologizing, they are putting themselves in a vulnerable position. If they are sincere, and you are willing to take the apology, say you accept, and either shake hands or make some conciliatory move.

If you are not willing to accept, either because the offense was too great or the apology too late or too insincere, then civilly tell the person you appreciate their effort but the you do not feel it was enough/sincere or what ever reason. Then walk away and get on with your life.

Any other response (say the movie dramatic effect of a slap in the face) would put you in the position of the offender and require an apology from you for your behavior.
