"Where do you get your ideas?"
Every writer hears this question, and it's easy to respond with something cute, such as, "I order a dozen at a time from a P. O. Box in New Jersey."
Many times a snappy answer is sufficent. Sometimes, though, if the person asking the question is sincere, a simple explanation may be appropriate: "I ask myself 'what if?' What if my neighbor isn't digging a new flower bed, but is digging a place to bury his wife? What if a woman suddenly started hearing other people's thoughts? What if a man caught his wife cheating with another woman? What if a ghost suddenly appeared in a woman's bedroom? The story is how I answer that question."
But what if the person asking the question, the person who wants to know where you get your ideas, isn't interested in cocktail chatter, but is a potential companion--friend, lover, spouse, etc.--and is sincerely interested in how your mind works? How much do you reveal? (How much do you even understand about yourself?)
I have no answers, only questions.
