For one of my freelance clients, I encountered a story idea regarding a new business opening up. Editor liked it. But since I currently work part-time for a competitor, I had to pass on it and let her assign it to somebody else.
Reminds me how, a few years ago, I told another client about how my wife's Aunt C and her husband Uncle K fix up old cars and show them at car shows. One car in particular was the same type of car used by the infamous criminals Bonnie and Clyde. Editor loved it, but, since they're family through marriage, I passed on writing it.
