As it is an international era, my friends sometimes go abroad these
days and they ask me "hey, what do you want as a souvenior for you?"
... But I had never had any good ideas. 
So one day, I asked one of my friends to buy a national flag of that
country he was going to visit. I added one request to him; "please
buy a large size, its width would be over 1 meter." In some countries,
my request becomes a big difficulty if the patriotism of the
country isn't high.
My request is :
|   | [Nippon] I bought this by 3,300 yen although its price tag said 6,600 yen.
 | 
|   | [The United States of America] I visited USA in my graduation trip
(just before graduading Kyoto Univ). In USA, it was easy to buy it.

quite difficult to buy it. The hotel's concierge tought me a flag
factory shop where the hotel usually buys their flags. The shop

^_^ building.

true my speaking skill is quite poor.
