     Last Thursday, a young woman saved an elderly man from a burning house on Garden Road. The young woman’s name is Kitty and she works in a clothes shop. The elderly man, Daniel, lives just opposite the clothes shop. On Thursday afternoon, Kitty looked out of the window. She saw some smoke coming from Daniel’s house and rushed over to see what was happening. The house was on fire and Daniel was inside. Kitty quickly called the fireman on 999. Then, she ran into the house to save Daniel. She found Daniel in his bedroom and he was frightened. Kitty helped Daniel out to a safe place. Five minutes later the fireman arrived and they put out the fire. No one was hurt.
The next day, Daniel said,“I am so grateful to Kitty. She saved my life.”Daniel also said,“In the future, I will be more careful. I don’t want another fire in my house.”
