Visitor (V): "Good morning. It's a beautiful day."
The man nods.
V: "There must be a lot of fish in that sea - why don't you go and catch some?"
The local man (L): "I've already been out this morning - I've caught some fish today."
V (after a pause): "Well, you could go out again and catch some more fish."
V: "Well, then you would make more money."
L (pauses): "Why?"
V: "Well, then you could buy a bigger boat, and catch more fish."
L (pauses): "But why?"
V: "Well, then you would have more money, and you could buy another boat. You could own several boats and have people working for you. You could open a fish restaurant and..." (the man gets quite carried away with his ideas)
L (pauses again, and looks at the visitor with a puzzled look): "But why?"
V: "Well, then you could sit here all day, and enjoy the view and the fresh air."
L (with an incredulous look on his face): "But that's what I am doing now."
