One day MrEarnshaw came back from a long journey. He had travelled sixty miles to Liverpool and back on business, and was very tired. “Look what I have brought you!” he said. His children, Catherine and Hindley, were expecting presents and they rushed eagerly to see what it was.
They were very disappointed to see only a dirty, black-haired gipsy child. “I found him all alone in the busy street of Liverpool”, MrEarnshaw explained to them, “and I couldn’t leave him to die. He can sleep in your room, children.” But Catherine and Hindley were very angry because they hadn` t received any presents, and refused to let the strange child share their room. However, MrEarnshaw insisted and, and little by little the boy became accepted by the family. He was called Heathcliff, as a first and last name. No one ever discovered who his parents were.
Catherine and he became great friends, but Hindley hated him, and was often cruel to him. Old MrEarnshaw was strangely fond of that gipsy child, and frequently punished his son for behaving badly to Heathcliff. Hindley began to be jealous to his father’s feelings for Heathcliff, and saw them both as enemies.
This situation couldn’t last. As MrEarnshaw grew old and ill, Heathcliff became even more his favourite, and Hindley often quarrelled with father. When Hindley was sent away to study, everybody hoped that they would have peace in the house-

I never stay in one country for a long time. It gets boring. I like to move on, see new places, and meet different people. It's a good life, most of the time. When I need money, I get a job. I can do most things - hotel and restaurant work, building work, picking fruit.
I like to go south in the winter - Cyprus, or perhaps North Africa. Life is easier in the sun, and Northern Europe can get very cold in the winter. Last year I was in Venice in October. I did some work in a hotel for three weeks, then I began slowly to move south. I always go by train when I can. I like trains. You can walk about on a train, and you meet a lot of people.
I left Venice and went on to Trieste. There I got a cheap ticket for the slow train to Sofia, in Bulgaria. It takes a day and a half, but the express was too expensive.
The train left Trieste at nine o'clock on a Thursday morning. There weren't many people on it at first, but at Zagreb more people got on. Two girls went along the corridor, past my compartment. They looked through the door, but they didn't come in. The train left Zagreb and I looked out of the window for about ten minutes, then I went to sleep.
When I opened my eyes again, the two girls were in the compartment.
'Hi!' they said.
'You're American,' I said. 'Or Canadian. Right?'
'American,' the taller girl said. She smiled. 'And you're twenty-three, your name is Tom Walsh, you've got blue eyes, and your mum lives in Burnham-on-Sea, UK. Right?
'How did you know all that?' I asked.-
