For many years I paid part of my family’s bills by writing confession stories. They are true stories and the author’s name is never given. I wondered how it would work using my own life experiences for stories. If I would be criticized.
The funny thing is, the few times that family was there when the free copy arrived in the mail with my story in it clearly marked for everyone to see, no one recognized the story they read as something that had actually happened. They complimented me on my imagination.
I think that happened because everyone sees events differently. I once heard a writer say that ten writers could write a faithful description of the same event and no two would be even remotely similar. I suspect he was right.
So, you simply tell the story however you wish, changing names and places and any other identifiable material. Then let your readers enjoy the story they are reading that they think is fictional because they don’t recognize a thing.
