In This Body Mystery, even though it was written in the voice of people with HIV/AIDS, it's about how people come to accept their fate and their sickness. It's about accepting the way your life is.
Whether I affect one person or an entire family, or even a group of people, I feel like I have resources and education and ability and skills that some people may not be fortunate enough to acquire. But by sharing and inquiring, being a listener, and being interested in the stories of other people and their lives, I can also pull things out and say "What can I do for them? What can I share with them that may alleviate some of their suffering?
Even though I'm not privileged in the money world, I'm privileged in other ways: I had greater access to education, I can travel, etc. It's the same with writing: the freedom to move in and out of different places, of different realms of existence, of different life forms.
