There is always one-original

Near my house, there is a cow crossing.  The cows walk across the road twice a day to get from barn to field, and then back to the barn later in the day.  It is a pain in the neck to get stuck on the road waiting for all the cows to get across.  They are in no hurry! It always seems to me that there will be one cow who stops and looks me in the eye as she chews her cud.  She knows she is in control.  I  can not go on my way until she decides to move!
