İt was Friday evening. My brother and I were in his bedroom. My parents were at work, so they weren't at home. My brother was bored. I wasn't pleased because my favorite sports programme wasn't on TV. Then there was a noise. My friends,Jack and Nick, were at the door with three DVDs and a huge pizza. The DVDs were horror films and the pizza was fantastic .What a great surprise!
