Wherever you go and any building you enter, business or factory, church or government body, there is one person in charge. Households are the same way. Someone must be responsible for practically everything. In the military your leaders will be clearly marked with stars, stripes or bars and higher-ranking officers have authority over other soldiers. In a cheerleading squad one girl will be the head cheerleader. With a baseball, football or soccer team the coach is of course in charge. He has to win or get another job.
