It was a full-moon's night. Bright moonlight flooded the road. I was walking slowly. Suddenly, I heard a whistling sound. At first, I thought it was another late evening stroller like me. The sound was loud and cheerful. Suddenly, a boy on a bicycle sped past me. I could not see his face. After a few minutes he was back again. This time he stopped a few feet away from me and gave me a smile. He looked like a slim boy of fourteen. He wore a school blazer, a cap and a scarf. His eyes were bright and cool like moonlight. "You don't have a bell on your bicycle," I said. He said nothing. I put out my hand but he did not take it. Then quite suddenly he sped past again. The next day l learnt that, that whistling boy was a ghost!
