I share only some of what I write with friends and family. The problem with such sharing is that friends and family are often part of my stories, though I don’t always mention their names unless they are dead and it won’t matter to them. I deeply offended one friend by letting her see a story I wrote about our college years. She had been one of my roommates. I haven’t heard a word from her since I shared that link.
I thought the story was humorous and I had no idea she would see it differently, but I guess she did. When I gave her the links we had been out of touch for at least forty years. We found each other online. I never mentioned her last name in what I wrote and it’s unlikely that anyone would recognize her unless they (1) happened to see the article (also unlikely) and knew us extremely well while we were on campus. The article was on a site few people have even heard of.
Now I’m very careful to keep other living people out of my stories. And it’s very hard to tell some stories about myself without mentioning people still living.
