Remember when Obama's people compared him to his basketball style? Team player, good D, takes the open shot. On and on. They think playing sports shows a person's true nature. And yours, my friend, is coming dangerously close to yes-man territory. Her dad wants to win, but he doesn't want it handed to him. So show him what you're made of. Stay cool and compete. Enjoy the challenge. That makes you worth his daughter's trust.
