A JIPSY CHILD
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
