Too often conversations fall prone to it and we end up not listening to the other person's story but recalling and rehearsing our own in our head so we can trump their story. We all do it at one time or another when really we should just take the time to listen to and fully appreciate the other person's story.
Monty Python's Four Yorkshire men is a humrerous ditting sketch.
But closer to real life is the scene near the end of the movie Jaws where Brody, Hooper and Quint share their "scar" stories.
