culture

Each countries have different cultures, which make the countries characteristic.
The most strange(?) culture, I think, is taking off the shoes before entering the house in Japan.
I always take off my shoes when I enater my house of course, but I feel it is a litttle troublesome.
I want to live in the house which I do not need to take off my shoes in the future.
Next is the strange culture in foreign countries.
It is sometimes usual to hug someone when they meet or leave.
When I stayed a farm in Australia, the host mother hug me when I leave the farm.
Of course I know foreign countries have culture like that but  it made me very surprise.
Did you experience some surprizing strange culture in some foreign countries?
Please tell me about them!
