You're facing the wrong way. In a cinema, a lady turned round and said to the giggling schoolgirls 
  behind her: "Do you mind, I'm trying to watch the film." 
    "In that case," said one of them, "you're facing the wrong way." 
你看错方向了
     剧院里,一位女士回头对后面正在说笑的一群女学生说:“如果你
  们不介意的话,我想看这场电影。” 
    “要是那样的话,”其中一个女孩子说,“那您肯定是看错方向了。”
