Have you ever apologized for something many years after it happened, or been apologized to after many years?

I just wrote an old friend on Facebook apologizing for being really mean when we were ten. Before I went through my mean phase, we were the very best of friends. Her sister found me on FB and then my friend “friended” me or whatever you call it. I felt like I was in that scene in Billy Madison if you recall it. Anyway, it felt good acknowledging that I had hurt her and I wished her happiness in life.
