N

 I decided to look for Bob N.  I hadn't seen him for 40 years.  I wanted to talk, but  I no longer had his home address. I managed to find it on the Internet.

Bob was an intelligent, trusted old friend. We'd parted ways one day in Buffalo when our wives had gotten into a discussion of different approaches to child rearing, and my wife had told his to fuck off. 

Through the university where he had worked, I learned that Bob had sold his house twenty years ago. I don’t know where he went next. And he died three years ago.
