When I went to Australia for a trip, I had an experience that people hugged me before saying good-bye. I was born and brought up in Japan where hugging or body contact is rarely seen. It's been changing, but still public affection is not shown so much in my country. ( Even between the lovers, they hesitate to hug in public. Of course they do when they are alone. ) So I almost stepped back when I was about to be hugged... That was my first culture shock in my life.
