（主题：An Unforgettable Storm）

An Unforgettable Storm

    Last Saturday, I experienced a terrible storm. It started at around 7:00 p.m. I was doing my homework when the wind began to blow hard. My sister was playing with her toys in her room. My mom was cooking dinner in the kitchen, and my dad was reading a newspaper in the living room. 

    Suddenly, the lights went out. The rain was beating heavily against the windows. My mom lit candles and we sat together in the living room. We talked about our day and told stories to each other. At that moment, I felt so warm and safe with my family around me. 

     When the storm finally stopped, the sky became clear again. The storm was scary, but it also let me know how much my family loves me. I will never forget this experience.
