I had to deal with both parents and many people who were patients in the back of the ambulance. Today at 70 if I forget I tell people that is what happens when you get knocked off a Harley Trike at 70 mph no helmet. They smile and know I am telling the truth!
Don't feel bad,I have been called by people and have asked who did this cabinet job and they say you did. Of course it was over many years ago. I usually put things out of my mind after the job is done and move on to the next thing. You can't remember every nail you've driven.
