You made a bridge for me circa 1969 when I was a graduate student in the Philosophy Department at Northwestern and you were in dental school. It must have lifted a little and I had to have a root canal circa 1981. But the guy who did that left your bridge and I’m just now having it replaced. My local small town guy is incredulous that your student bridge lasted 45 years. He can’t think of a similar story. So, out of nowhere I’m writing to say thanks for the great work. I could have drawn the C- student, and instead I got you and enjoyed 45 years of your great dentistry. This is not the first time I have been glad that you were a talented and conscientious student who did great work; it’s just the first time I decided a ghost from your past should pay you a grateful visit.
