It was in the time of twilight. It was not dark and not bright, nothing foreshadowed, the children were playing I was sitting talking to a friend. We decided to see what the weather is like tomorrow. In the news they write about the threat of a tornade, I quickly ran home with my friend. We fled from all our strength, but we still saw this catastrophe, Tornado. Cars wind blew, rain, people asked for help. The animals also tried to escape, but some took the tornado. We could come home, look out the window and say "When will it end?"
