A friend of mine introduced me to this woman I'm going to meet in person on my impending book tour to Tacoma, and we've been texting to get to know each other a little. Suddenly, this morning, I started getting these weird texts - about how she's got a live-in boyfriend and needs to break it off with me, and then apparently the boyfriend gets a hold of the phone and starts texting to me directly about how she's a cheating, lying so-and-so, and he discovered her texts to me, etc.
Problem was, there was something about this narrative that was terribly phony. Very obvious use of exposition to plant ideas in my head. Unnecessary facts. And, for a guy who's supposedly just been cheated upon, way too much concern for his rival's feelings. As fiction, it just didn't hold up - it was like a really poorly written novel. So I didn't respond.
Turns out, the malicious ex-husband stole Lady X's cell phone and was trying to spread every lie he could think of to all her friends. But he didn't count on the super-psychic skills of Editor Man!
So see? Writing fiction can be useful in all kinds of ways.
