answer:Not exactly a fan letter, but I wrote a letter to an author that I really like, Anne B. Ross, who wrote the Miss Julia Series because I had very vivid images of who I thought should play her characters if her books were they ever made into a movie. She wrote back and was very thoughtful and seemed to enjoy that I had actually chosen specific actors. I also wrote to another author that I like, Nancy Thayer, about her Hot Flash Club Series and got a similar response. I had all of the main characters figured out, by what actors would play them. She was very sweet in her response. I also wrote to Michael Nesmith of the 60’s era musical group The Monkees, when one of his songs, “Mary Mary” was sampled (IMO illegally) in the 1980’s. I sent him a copy of the record and he signed it, thanked me for my concern and mailed it back to me : )
