I know how stupid people can be. I've played in front of 5,000 people that bought a ticket to my concert, and some guy who's bought a ticket decides he's going to throw a bottle at my head. That's a simple act of stupidity. That's not even defiance.
Its just as disappointing as it was thrilling to win the Masters. To come very close, to play so hard for 72 holes and play better than everybody but one guy is disappointing.
