It happens in the field, too, even though we rarely shoot the same target five times in a row. We do have days when we’re not shooting well, and often, when we’re not hitting, we start thinking. A bird, let’s say it’s a dove, since it’s that time of year, crosses out front. You swing the gun and, anxious not to miss again, start figuring out how much lead it needs. You examine the gap between bird and barrel, decide it looks good, and pull the trigger. The dove keeps going because the gun slowed down as you looked at the lead and not at the bird’s beak. Your pile of empties grows.
