It is often said that english are cold and unfriendly, but in fact this is because they are rather shy.
If you are a foreigner, there are a number of ways to get to know the english.
For example, imagine you are in a park where there are lots of people with their dogs.
Now, you can't say to someone, what beautiful hair you have! Even if it's true.
But you can say, what a lovely dog you have!.
This is a very good way to start a conversation, even of the dogs so much.
And who knows how the conversation will end?
