3. The Main Event in the Life of the Community

4. Being Friendly Is Natural for Village People

5. They Saw a Lot

6. We Can Rebuild the Past

7. We Still Need Them

A Icons of the English life, pillar boxes stand like red and black soldiers. Surprisingly, most of them are still with us. They are recognised even in the modern world of the Internet. We’ve always worried that these necessary items may one day disappear or that we might wake up and find them all painted yellow. But perhaps there is an agreement to protect them because of their important purpose.

В England is nothing without its ancient trees. People think there are some ancient olive trees in Greece, but they have not achieved the fame of, say, Newton’s apple tree in Lincolnshire. We name our trees. They almost seem to speak to us, telling us something about the long period of history they have experienced. It is wonderful that there is something living today that was 3,000 or more years old at the time of the first Christmas.

С The highlight of village life is the yearly fair, where the charities and local sellers have their sales; brass bands play; beautiful babies compete for prizes, so do dogs; children’s faces are painted; the bars attract customers; famous people play cricket; VIPs dress up and parade. The problem, of course, is British rain. Some villages also have a winter street fair, with Father Christmas instead of the carnival queen. A lot of people give months of work to these events, which are always visited by a great number of people.

D Bonfire Night is a holiday from the past, but it’s the modern effect I care for. It should be made a national holiday. People may disagree about historic events, but it is one of the festivals that involve a lot of different people. In London, people of all ages and nationalities go to the streets and to the parks to enjoy themselves and feel happy. It is like a group hug for the coming winter.

E The tree museum in Westonbirt is not just a collection of trees, but a gigantic and unusually designed park, with wide avenues, rides and narrow walkways. Every corner makes you feel excited. And what trees are here! There are sequoias, magnolias, rhododendrons, pine trees of every kind, from a very rare Australian plant to ones which are higher than office buildings in London.

F One day I was standing in front of my country house when a man, who I didn’t know, started talking to me. I thought I was prepared for all the things about the countryside that could make you feel nervous, the different kinds of trees, the emptiness, the bright colours of the wild flowers, but what I hadn’t been ready for was the friendliness. In London, nobody talks to you outside the house. That is why I was very surprised. But later I decided if I was going to live in the country, I should learn to be friendly too.
