Keep calm and carry on! You can see this message write on many T-shirt and other souvenirs in London and the UK. It has become very famous that there are many versions of it. But where does the originally phrase come from? Well, it comes from Second World War. It was the message used for a poster being created by the British government to calm people down and encourage it during the war. When London was being attacked, “Keep calm and carry on” with your life as normal, as if there were no war. Keep calm when you have problems is known as a very British thing to do. In the past British people are famous for keeping a “stiff tipper lip”. This means your lips don’t shake when you are excited or frightening: you stay calm and don’t show people how you are really. Do the British still like this today? Well, not really. However, they are still fond of this message.
