AT THE RAILWAY STATION

A steam engine was waiting. The first few carriages were packed with students, some hanging out of the window to talk to their families, some fighting over seats. Harry pushed his trolley down the platform in search of an empty seat. He pressed on through the crowd until he found an empty compartment near the end of the train. He started to move his suitcase towards the train door. He tried to lift it up the steps but could hardly raise one end and dropped it painfully on his foot.
“Want a hand with it?” a red-haired boy asked. “Yes, please. That’s very kind of you,” Harry replied.
