     In England, people don't usually talk very much. You can get on a bus or a train, and everyone likes

looking out of the window. Often they read books and papers. But they don't talk much.

     When you meet English people, they often talk about one thing-weather. So  when  you  meet your

friends in England, you can say," Nice weather for the time of this year ! "

    "But it was a little cold yesterday. " Someone may answer.

    "But it got a bit warmer later!" You can say.

     Talk like this, and the English will think," How friendly you are!"

never has the same kind of weather for a long time. In spring, sunshine and rain follow each other quite

often during the day. So when one goes out, he must never forget to take an umbrella.
