people who have had amnesia before, what was something that people said that they thought you would forget but didn’t ?

I had a friend who, after I got my amnesia, told me that he was sorry for all the bad things he had done to me in the past. It was like a weight had been lifted off my shoulders and it’s something that I never forgot. He said it was something he thought I wouldn’t remember, but it stayed with me like an indelible mark on my memory.
