     If you have a chance to go to Finland, you will probably be surprised to find how "foolish" the Finnish

people are.

     Take the taxi drivers for example. Taxis in Finland are mostly high-class Benz with a fare (车费) of two

US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you

have some business to attend to, and then walk off without paying your fare. The driver will not show the

least sign of anxiety.

     The dining rooms in all big hotels not only serve their guests, but also serve outside eaters. Hotel guests

have their meals free, so they naturally go to the free dining room to have their meals. The only thing they

need to do is to wave their room cards to the waiter. With such a loose check, you can easily use any old

room card to take a couple of friends to eat dinner free of charge.

     The Finnish workers are paid by the hour. They are very much on their own as soon as they have agreed

with the boss on the payment. From then on they just say how many hours they have worked and they will

be paid accordingly.

     With so many loopholes (漏洞) in everyday life, surely Finland must be a heaven to those who love to

take "small advantages". But the strange thing is: all the taxi passengers will always come back to pay their

fare after they have dealt with their business; not a single outsider has ever been found in the free hotel dining

room; and workers always give an honest answer of the exact hours they put in. As the Finns always act on

good trust in everything they do, living in such a society has tumed everyone into a real "gentleman".
