Rob's story

Part I

I come from the future

I come from the future. I lived in London in the twenty-first century. I had a big family, but I didn't have any friends. I thought that I didn't need them. One day our school teacher brought us letters from children in Russia, and we answered them. My pen friend was Misha Inin. One day he invited me to Russia. I was really excited. I didn't know much about Russia and it was really interesting for me to visit it.
Strange things started to happen from the beginning. When I came to Russia, nobody met me at the airport. I waited and waited, but nobody came. I got angry with my friend and decided to buy a ticket and fly back home. But before that I wanted to leave the airport and look at a Russian city.
The next moment I was in a narrow and dirty street. The air was bad and the smell was horrible. There weren't any cars, but I saw a lot of horses.
The people scared me. They had gloomy faces and their clothes were dirty.

I got lost and had to stop. Then a window opened, and a pile of rubbish fell on my head. The place was very strange. I was shocked and wanted to call the police.

Finally, I found a man who looked like a soldier. I spoke Russian to him. But he answered in English! I asked the soldier about the police, but he didn't understand me.
It was dark and cold and I didn't know what to do. "Give me some food!" I said to the soldier. "I have no food for beggars, but I need a servant," he replied. "I am one of Queen Elizabeth's knights. I have a secret mission in this dirty city of Edinburgh and I need a clever boy like you."
"Elizabeth! Edinburgh!" I thought to myself "These Russian jokes are very strange." But I decided not to show my feelings and said to the soldier, "I'll be happy to become your servant." "Good," he answered. "I am staying in this inn. Clean my horse, wash my clothes and cook dinner. Here is some money."
I didn't do anything, but I used the money. I bought some bread and some soup. The food wasn't very tasty, but I was hungry and had to eat it.
When the soldier came home, he was very angry. He beat me! After that, I had to cook dinner for him and he went to bed. The situation wasn't funny, I wanted to phone Mum and Dad, but I couldn't find any telephones.
Then I decided to go to bed too, but there wasn't a bed for me. I had to sleep on the floor. I didn't understand anything and I felt very unhappy.
