I have always paid attention to conversations around me, I never knew why, except that it can be really fun trying to figure out why a person said what I heard. Then in the military, I was in the Security police, so listening was encouraged. Now, I do it, noticing how people talk, what they talk about, and how they say it. The one famous line of a song written by an eves dropper; "...And then they tased her again." He wrote the whole song based on that one statement. So did you listen to others before becoming a writer or after, or don't you do it know? I don't know how anyone can write good dialog without listening in on others, so if you don't listen in, how do you write dialog?
