It's really interesting that this old thread would come up today. Perfect timing.
I was working yesterday afternoon in the proshop at the golf course when 3 high school golf teams came to play a match. With our good year round weather, it's hard to imagine these schools were already playing their last matches of the year.
Two of the schools got out slightly earlier and the kids hung around the shop while they waited for the last school to arrive. I knew one player from the school where my kids went. His brother had worked with me before and I eventually got to know the whole family. Tony introduced me to his team mates and when the other school got there, one of Tony's team mates0 introduced me to his cousin, who was on the other team and to their whole school team.
I'd like to believe golf has had such a positive effect on these young men that it's the reason for their good manners. These were pleasant kids to be with and talk to. When they finished, most of them came in the proshop to say goodbye, the exceptions having been rushed off by parents who waited for them.
In the official USGA Rules of Golf, the etiquette of the game is in the front of the book, before the rules of how to play the game. I'd like to take that to mean being of good character is primary to how we play this game. In the case of these young people, I think it's carried over to their behavior, not to mention I congratulate their parents on how they have raised them.
