I have never seen a famous person. For example, an actor, comedian, musician and so on. Have you ever seen such a person in city? I often go to Tokyo's lively area (Shibuya, Shinjuku etc.), but I've never seen any. I may be terribly unlucky. According to my friends, they saw a famous comedian in Japan. I want to see a famous comedian or an actor at least once. Of course, I have seen them at the cinema/theatre But that is a little bit different. In a theatre , the audience expects to see famous people. I think that the important point is "surprise". In the city, I would be very surprised if I saw famous person. This emotion might be so important.
