Rupinder was sitting by himself in the house.It was an important day.Today he and his family weregoing to leave their village.They were going to emigrate to England.He was feeling very excited and sad.He was feeling sad because he was going to leave his home, his village and his friends.He thought: ''I will miss them all.I will probably not like England.I will probably want to come back.'' 2. Outside there was a crowd of people. They were his relatives and his neighbours.They were all waiting for the bus to Jullunder,the nearest town.There they could take a train to New Delhi.In New Delhi they wanted to take their plane to England.Everybody was going to travel to Jullunder with them to say goodbye.His parents and his sister,Hardeep,were outside,too.He could hear them talking.Hardeep was very excited.She was laughing and talking to her two friends:"We are going to lsve in England.We are going to travel in a big plane.We are going to live in a big house.And i am going to go to an English school."She was very happy. 3. "Oh,look!Here's the bus.Where is Rupinder?""Rupinder!Where are you?It's time to go."Everybody got into the bus.It was very crowded inside. There was a lot of luggage on the uoof.The driver fixed their boxes onto the roof.It was not far to Jullunder.It only took an hour. 4 . At the station everyone waited for the train to New Delhi.Everyone was laughing and talking.Two of their neighbours put garlands of flowers round their necks.Grandmother gave Rupinder some sweets and oranges in a basket.His best friend gave him some cakes."You are a lucky boy,Rupinder.I would like to go,too.Write to me.Don't forget me.Send me a postcard of London." Then the train came.It was a steam train.Hardeep was frightened."I don't like the noise.Idon't want to go.""It's all right,Hardeep.It's guite safe.Look at all the people on the train.Come on.Get in here."The father found four seats for them.Everyone was shouting:"Goodbye!Goodbye!Have a safe journey!Write to us when you get to England.Goodbye!"Their grandmother was crying and their relatives looked sad. 5. It was a very long journey to New Delhi.It took eight hours.The train was hot and crowded.Hardeep was excited and impatient."How far is it to New Delhi?What time shall we get there?"Rupinder was guiet.He was looking out of the window.There were men working in the fields."Look,Hardeep,there's a baby donkey with his mother."But Hardeep was asleep.Soon Rupinder was asleep,too.
