I’m not sure why people tend to assume that all fiction is autobiographical, but on the other hand, I think it often is, at least to some extent. Writers write about things that interest them, and many of us are inspired by what we see in our own lives.
When people ask me if The Weird Sisters is about my life, my answer is typically, “More than I intended, and less than you think.” The three sisters’ personalities are based on parts of me, and some of the plot is concerned with things I saw happen to friends. The themes are absolutely things I was trying to figure out myself: birth order, adulthood, family communication.
But The Weird Sisters is fiction. It’s just filtered through my particular way of seeing the world, so in that way it is autobiographical.
Do you expect that fiction is about writer’s lives? Where’s the line to you between fiction and autobiography?
