A Lucky Accident
It was a cold winter morning. I was walking to school with my friend Tom. We were talking and laughing about the weekend. Suddenly, Tom slipped on some ice and fell down. He couldn’t get up. His leg was hurting badly.
While I was trying to help him, a woman ran out of a nearby house. She was a nurse. She looked at Tom's leg and said, "Don't move him. I'll call an ambulance." Soon, the ambulance arrived and took Tom to the hospital.
Later, we found out that Tom’s leg was broken, but he was lucky. If the nurse hadn’t helped so quickly, it could have been worse. From this experience, I learned that we should always be careful when walking on icy roads. I also learned that helping others is very important.
