Let us agree that there is a precipitating event (or events), and that actual emotional or physical harm was done. Not just once, actually. And let us also agree that this was made clear to the other party. For example, "hey! you just stepped on that guy's foot" or "I don't like it when you say ....", etc.
So, should the response be
1. "I'm sorry I hurt you"
2. "I'm sorry you were hurt"
3. "Your/their [emotions/toes] will stop hurting long before my pride does"
(the above brought to you by reality, not necessarily mine)
