Truthfully, pretty much all of the stories I write have some basis in my life.
Oh, I may play around and write from the female perspective when I was actually the guy in the reality it was based on. Which, of course, means I couldn't have had a clue what was going on in her head and so had to base the thoughts I attribute now to what she said and did then.
And, of course, I leave out the boring details. Like exactly how long she was in the bathroom and how close I was to falling asleep by the time she came back out.
And the conversations were probably a lot different. Even when I can remember what was said, it just doesn't read the same as it sounded. So, I have to pretty that part up so no reader says, "Dude, I'm surprised you've gotten laid yet, much less then!"
Since I am currently working on short, short stories to break out of my bad habit of taking twenty-four pages to describe a sex scene, I have to condense quite a bit. I have to make what in reality took about seven hours read like it only took thirty minutes.
And, yeah, I change up the names to protect the... um... can't really say innocent. Well, to protect the identites of the people in question and thus me from their lawyers.
You know... come to think of it, it's just about all a pack of lies, isn't it?
The difference between genius and stupidity is usually the audience.
