At the midnight, thunder was crashing and the rain was pouring. Suddenly my father rushed into my room. “Adam! Adam! Get up! We're flooding!” he shouted and shook me by the shoulders. That woke me up! I ran downstairs to the basement (地下室). It was like a swimming pool. My mother and I immediately started to pick up things and take them upstairs. I had no shoes on, so my feet felt quite cold.

Things got worse every minute. Within the next hour, we had moved everything that we could to the first floor. The computer, big-screen television and heavy boxes filled with our most valuable things were taken to safety. However, our piano, sofa, washing machine and water heater were all still down there — being destroyed. There was nothing we could do.

That was the hardest part. Knowing that your home is being destroyed is bad enough, but realizing that you can't do anything to stop it feels even worse. Water had come in our front door. Rescue boats were floating in our streets. Mother told me to pack an overnight(通宵, 前夜) bag of clothes and valuables and get ready to leave.

When it was finally safe to walk outside, all the people in the neighborhood gathered at the street corner. People became friends, and friends became like family. People comforted each other. We learnt later that the National Weather Service had declared (宣布) the storm a flash flood.

I really have learnt something from this flood, I've learnt what destruction is. I have learnt what safety means. I know in the future, when I watch people's lives affected (影响) by natural disasters, I can understand them. I will show my great pity on them and I will do what I can to help them.
