To be honest, I've met, spoken, and kept company with many Chinese women, as they're everywhere in my town, but I've had contact with a Japanese woman only once, in one of my first Greek classes. She was very shy indeed. Very kind, but didn't want to go out with us after class, she always had a lot to study and seemed reserved on most of the topics. Otherwise, very nice, and I felt sorry I couldn't make her to be friends with us. But I remember she showed me how to write my name in Japanese :)
