When I was a child, my parents always told me that I should never talk to strangers. This was part of a whole list of things I should never do: Never accept food or candy from strangers, never get in a car with strangers, and so on.

But if we didn’t start a conversation with strangers, we’d never make new friends. We’d never get a job. We may miss the joy that comes from talking with strangers. And the more people you know, you more chances you can get.

The following passage offers you some advice on how to break the ice.

Don’t just stare at your shoes. Go and say “Hi” to that new guy. It will be easier to break the ice if you know more about different cultures.

British: Beautiful day, isn’t it?

The weather in Britain is changeable. So, it is one of the topics the British care most about. And there’s a simple rule: Say “Yes” whether you agree with the person’s idea on the weather or not. That’s because the British start a conversation using the weather so that they can continue their talk.

French: Where did you go on holiday?

To talk with a French person, the safest way is to ask his or her last holiday. French students enjoy a 10-to-15-day holiday every two months. French employees get more than six weeks of holidays per year.

American: So, where are you from?

The US is so big and people move so often that location is always a source(来源) of talk. You can try to find a connection with the place they’re from. For example, if someone’s from Los Angeles, you could say:“Oh, I have a friend who studied there”
