Last Saturday evening my parents were away and I was home alone. I was bored, so I invited some friends over. When they came they brought some CDs with them, and we decided to have a small party. While we were dancing, my best friend Lisa knocked over a small table. Mum’s favourite vase flew up in the air and crashed against the TV. "I’m so sorry! I didn’t know it was behind me, " she said. I was so shocked! As I was trying to clean up the room, the lights went out and we couldn’t see anything. Unfortunately, Lisa’s brother Tom slipped and hurt his knee. I was disappointed my party ended up badly, but there was even more to come. As my friends were leaving, my parents were arriving home. My Saturday was spoiled and so were the next few days.（）
