Especially, I was surprised to see that German people kiss on the street without caring another people. It is the unthinkable in Japan. If you had an experience staying abroad, Japanese would not do it in front of people because we think it is a ashamed and feel embarrassed. I have discussed about it with my host mother. She said it is an expression of their love and asked me why we do not do it. Though I could not explain it her well, she seemed to understand when I said we kiss not outside but at home. I have another idea about it. I think that Japanese people think we do not deserve kissing each other on the street. we admit that if you were like movie actor or actress,(at first, I had written "movie hero or heroin", can you understand my mistake? lol) you can do it in romantic place. but not normal people because it is not perfect for a picture.

How is your country?
