I was walking home from school while suddenly it rained heavy. What should I do? I didn’t have an umbrella and a raincoat with me. I looked around and   see some students walking happily under their umbrellas. They must listened to the weather forecast. I began to run and caught in the rain. I kept running until I got to a bookstore which I could wait until the rain stopped and in the same time I could read my favorite books. After about half a hour, the rain stopped and I go home.
