I began responding to emails politely and distantly, a few of the writers were a little too wacky, so I only sent a brief acknowledgement, not going into details.
Most of these didn’t bother me again, a few I had to block.
Two of my correspondents, who were not all that wacky were avid. They didn’t seem to have much life. I wound up answering their emails almost every day.
I began to invent ‘backstories’ for various ‘events’ in the actor’s life. I did a bit of cut and paste from the posted biography, and a lot of fiction.
As I made my money as a writer, it wasn’t a big deal to write a paragraph here and there.
And then, the idea took me.
I began a short story which encapsulated what I was doing with these two fans.
