An old friend I met bowling once took me AND his girl golfing with him, I think mostly to see how bad I would do.
He had taken me to the driving range several times before we went to bowl or drink, and could not break me of the habit of 'stepping into it' like a pitch.
We were on a course with 9 holes going one way, and the second going back towards the first. so he instructed us both, if we heard 'FORE!' to look at him, and follow.
About the 6th hole,we heard it, and Laura immediately looked up, bewildered, wondering what it meant.
About 4 seconds later, we were trying to scrape her off the fairway and wake her up, despite the big red lump in the middle of her forehead...........
