I remember that tradition. My dad would get out of the car and put his hand over his heart if we were in rural areas.
This is a real oldie:
Two men are playing golf on a beautiful Sunday afternoon. As they approach the 10th tee they can see a nearby road. Just before they tee off, a funeral procession passes by on the road so one of the golfers takes his hat off, faces the road and holds his hat over his heart.
The golfer’s partner says “That is very kind of you.”
“Not at all,” the golfer replies, “After all, we were married for 42 years.”
With golfers, it might be true!
