Unusual Culture

The most unusual custom I've ever seen is Brazilian way of greeting.
When Brazilian people see their acquaintances, they often press their cheek on each other and make lip sound.
When I went to Brazil about five years ago, My host mother did me that, which surprised me a lot. People in Brazil can make lip sound very well. It's like the sound we make when we kiss. I couldn't understand how to make it well at all.
During my stay in Brazil, I realized that different culture can lead to misunderstanding.
Let me tell you what I experienced when I leave Brazil.
When I said good-bye to my friends in Brazil, a girl came up to me and then she pressed her cheak on mine and made a lip sound. I mistakenly believed that she loved me and I was about to kiss her cheak haha
After all, what she did was just a brazilian way of greeting.

If I could add one custom to Japanese culture, it would be hugging as Kevin said in his blog.
Hugging among family and friends give us happiness and joy. In addition, Patch Adams,who I really admire tells us how important it is to hug each other when we get sick.
I hope huging will wide-spread in Japan in the future.
