Girls play sports? While the coach seems to be a tyrant, in the long run it's good for the girls. Behind every successful man, is a woman who's able to support his career by making sure supper is ready when he gets home, is a lively guest when they go to the boss's house, and can keep the children in line while the man concentrates on his career.
Showing up 15 minutes early for practice shows the girls that you ALWAYS be prepared 15 minutes early for when the husband comes home, ready for a good meal, footrub, watching sports, and keeping up her looks for the times the man has a little hanky-panky in mind.
