Last Friday I saw the worst weather in years. In the morning, the sun was completely blocked so that I could see something clearly. I stayed at home, look outside. That came into sight was a flash of lightning. Seconds later, the noise of thunder broke the silent. Then a strong wind starts to blow into my room. Pieces of paper on my desk was blown high into the air and some flew out the open window. Then I closed the window when it rained hard and near broke my window.
What a bad weather! I hate it so I can't go out to play.
