I joined a meeting held by a volunteer tour guide group yesterday. An American young guy gave us a lecture about foreign tourists. He was a 23-year-old New Yorker.
After his presentation, he allowed us some questions. The questions should be related tourism or so. But some member asked a weird question. He asked, "before World War 2, we have lots of reminded original castles here in Japan. During the war time, the U.S troops were bombing many Japanese city and destroyed historical landmarks including castles. Now, we have only 12 of them. What do you think of that?"
The atmosphere there was frozen. Obviously, he shouldn't ask that kind of question at the time. If he really wanted to ask that, he should ask him after they made a trust relationship and in private.
