Don't go down her path. She sounds like a rather poor sportswoman. I'll tell you the basics of a hole all day long, and then throw a better shot than you. No need to lie. Failing to help someone look is a courtesy violation, and it seems like not telling someone a rule would be as well. I'm not trying to pick on your friend, I know plenty of people like her, and my comments are more about this category of person in general. People who have to enforce every nitpicky rule on everyone around them, but then don't follow the rules themselves in order to gain competitive advantage. They're fun to beat, as it usually results in a temper tantrum, or at least some serious whining. Either one makes me laugh on the inside. Plus they run out of playing partners quickly, as their abrasive attitude wears on all around them. You can develop a "killer attitude" without being a jerk to everyone around you.
