I had a somewhat similar situation. I was a few months sober and was working down the aisle (grocery store) from this guy. All of a sudden, I remembered that I had hit this guy in the face with a car door (on purpose) and laughed about it. I wasn't sure if it was true or if it was something my brain made up. So, I went down the aisle (scared to death) and I asked him if there had been an incident with a car door...
He got a bit angry, said yea, I broke his nose and 2 of his teeth. I made direct amends there on the spot. We were both able to put it in the past and able to have a "normal" relationship.
