I agree with you. In my case, I waited until a person I had wronged 30 years before reached out to me on facebook. Her contact gave me the opening to apologize. She claimed to have forgotten the incident, but I don’t think that was true (for complicated reasons). But she accepted my apology.
We became close again for a while, but then she quit returning my calls and I let her be. At least I got to make my peace.
