Do you have foreign friends?
I don't have foreign friends and I have never talked with foreigners without my teachers. Eye contact is important, I think. If you are not good at speaking English or other languages, you can communicate with foreigners. Also jesture is important, too. Though I can't speak English well, I want to talk with American to use big jesture. But when I talk with someone in language expected Japanese and English, it is so difficult to communicate. I think expression is important to judge feeling of someone to talk to, for example, if he speaks in a mechanical way, we begin to think he doesn't feel fun.
Sometimes I see Japanese who married person of other country. I want to know where they met or how they live, and so on. Maybe there are a lot of differences between them so I am really interested in international marriage.
