English translation.

When two foreigners (British) meet, the first sentence will be "How are you?" Answered "How are you?" Or "Fine, thanks, and you?" They often talk about the weather. They talk about it not because the weather there is interesting and always changing, but because the British don't like to talk about personal problems with people who are not friends. Talking about the weather is a useful way to start a conversation with strangers in public.
