Last Saturday, I, with a friend of mine, were having a picnic in a park when it began to rain heavily. We packed everything up rapid and were ready to leave. My friend, her hair was already wet, suddenly couldn't move and speak. Her eye were rolling and she was about to lose consciousness. I was so frightening that I didn't know how to do. Luckily, a woman on a bicycle appeared. Struggle with the rain, she managed to call an ambulance. My friend has recovered the next morning. I am so grateful for the woman. But I haven't even got chance to thank her.
