    Even nowadays there are a lot of misunderstandings between nationalities. Let's have a look at what the following people have to say.

Maria Conti: I find the English people insincere (虚伪), cold and unfriendly. They keep saying "Thank you", "I'm sorry", even when they don't know each other. They are even polite to their own relatives! Except for helping you find your way in the streets, they aren't really friendly and never invite you to their houses.

Giannis Sinios: On the contrary I found them both broad-minded and friendly. I was invited to people's houses and they all showed great interest in my ideas, Greek life and people. In England I learned that it was possible to be warm, friendly and polite at the same time.

Judy Brown: I lived in both Italy and Greece for a few years. At first there were a few misunderstandings between my foreign friends and myself. For example, I once gave a Greek friend a present for her birthday. I was rather sorry that she didn't unwrap it immediately. What's more, she even didn't thank me until I asked her if she liked it! I've learned from different experiences that a lot of foreigners find our attitude to what we English people call politeness is rather insincere. They feel that politeness isn't necessary between friends.
