On Sunday, Miss Green told Lisa, Jack and Lily a story about a girl names Cathy, who is just 12 years old. One day, when she was at the home, her mother careless cut her finger, which immediately started bleeding. As a little girl, Cathy didn't get a panic. Instead, she calmly cleaned her mother wound and then stopped it from bleed. She did that so she had just learned how to give first aid. Then Miss Green encouraged both of them to learn more about first aid. “It's really important because it can not only helps deal with injuries but also save life,” she said.
