I was happily typing up my homework on my new laptop when I heard a loud bang. It sounded like it was coming from outside so I looked out of the window to see if I could see anything, but I couldn't. I could only see a few people walking. It must have been someone gardening, so I decided to keep on typing. Then the bang came back and the sky turned grey. The people were still walking by and as the weather changed, they ran and sheltered under a tree. The sky was now bright blue! That was strange!
