Making a friend apologize in front of everyone isn’t justice. It’s a show.

A public apology serves the audience more than either person in it. The one apologizing is managing a room instead of talking to you, and whatever they say gets shaped by the people watching. You are unlikely to hear the true version in those conditions. What looks like accountability is usually just humiliation with better framing.

If you want the actual apology, ask for it somewhere with nobody else in it. One of you says what happened, the other says what they will do differently, and it is finished. Resist the part of you that wants everybody to see it, because that part is not interested in repair.
