For many golfers, the answer to this question is their father. Likely your father was a semi-serious golfer who enjoyed the game and taught you to enjoy it as well. Of course there are many of you who like me had another family member do the introduction. For some, maybe it was a friend even a friend's dad. Maybe you found the game on your own. Whoever it was, the day you finally beat that person is something that sticks in your memory bank forever.
My father didn't play golf. My mother sold his clubs a few months after I was born and she told me she did it because he never used them. He came home one day from work and they were gone. To many of you this is an unforgivable sin, but my dad shrugged it off and later said she was right, he never used them. Much later on in my golfing career he joined me a few times for scramble events. He liked to play in scrambles because there was no pressure and he could enjoy himself. He did not swing much past his waist and did not hit it very far. Looking back, though, he was in his sixties and not doing much stretching at the time. He claimed he was a good putter, but I never actually saw that.
