I'm a huge believer in the power of media, so I've gotten into the habit of referring people to films, documentaries, books and stuff when I break the news to them that I'm a bit different.
My current favourites are "Transgeneration" from the Sundance channel and "Middle Sexes: Redefining He and She" from HBO. Unfortunately my family and relatives' attention span does not stretch far beyond film, so no books, and I've stuck to documentaries to keep the drama factor lower.
So how do/did you ease them into it, or was it more a question of "that's me, take it or leave it"...?
